Bet MGM operates pursuant to an operating agreement with iGaming, Ontario. PJ, how have you been? I've been good. How have you been? Yeah, I'm a little better now having listened to your series.
I love it. Oh, thank you. Do you recognize that voice? It is PJ Vaux, host of the podcast Search Engine, and friend of Free Times Radio. You may remember hearing him back in 2024 when we published a search engine episode called The Fascinatingly Mundane Secrets of the World's Most Exclusive Nightclub about Burghine in Berlin.
That was a great story. And not too long ago, PJ came to us with another one. It's a two-part series on driverless cars. This is a topic that we have touched on many times over the years at Free Comics Radio, but PJ decided to go deep. The other day I had a chance to ask him how he got interested in this.
There's a whole lesson in this, but I'd gotten, and this is not the next answer you're going to expect me to say, too into bench pressing. That's not where I thought you were going. And I entered myself, I had a hernia, and then I had to have a hernia repair. I say, so there were like some minor complications. I was not moving easily.
I was in a lot of pain. So I had kind of limited mobility, and I was visiting a friend in San Francisco, and I took a waymo, and it was such an experience of the future that immediately becomes normal. First day I did that, I pressed it on my phone. A car would come out, I know. We're driven by nobody.
I would get in, watch the steering wheel turn itself. I was trying to describe this to me recently. I was like, the first time I feel like the first time you're in an airplane, and by the third time I feel like you're in an elevator. It was a moment where I thought, oh, a lot's about to change. And it was confusing to me that people were not talking about that more.
What should we expect to hear in the series? There are two parts. The first is really about the car, and then the second is really about the driver. Tell me who you think are some of the most compelling characters and why? So in the first part, there's this guy Sebastian Thrun.
He's a sternborn roboticist, AI expert who lost a friend as a teenager to a car accident, and he really thinks that his invention is not just going to make money for a tech company or be more convenient. He wants to reshape the modern world as it exists, and it's just the story of him and his team beginning to figure that out. And having ideas that sounded crazy 20 years ago, and with every year towards the present have sounded more sane and at least plausible. And then in the second part, I find the Boston politicians to be very vivid talkers, very very people. Vivid is a very bright word.
They're strongly opinionated. They sometimes commit gaps. When you ask them about the gaps, they are totally like, yeah, I screwed that one up. The thing that I most enjoyed about this story, which I'm always looking for, is that particularly in the second half, every time I spoke to someone, as they were talking, I thought, everything was saying, makes sense. I totally get it.
I would be nodding my head vigorously for the most part. And then I would go talk to the next person who saw things completely differently, and it would just spin my head the other way. And I would think, well, this makes sense too. And it was about trying to really do what I think we're all going to have to do a lot of soon, which is way competing, not totally reconcilable interests, and really take them seriously. And that was us trying to do it for this one thing.
I'll be honest with you, I've been anti-human driver for about 50 years now. 50 years? Oh, yeah. I mean, have you ever seen a human drive a car including yourself? We're not that good.
No, I have no illusions about my driving skills. I'm not that good. I'm, I have a temper. I am distracted. I rode in an autonomous test vehicle at Carnegie Mellon University.
They had a test track in Pittsburgh on an old steel mill property. And after this one 20 minute or whatever ride, I said, give me the autonomous vehicles. So plainly better than I am as a driver, certainly. So I'm eager for it. And I appreciate you're putting the pedal to the metal pill on this.
I hope it gives people a little context for this. All the questions people have is a safe. What's it going to do? Like we've answered as much as we can. Today on Freakonomics Radio, we turn the mic over to PJ and our friends at the Search Engine Podcast for the first of a two part series on driverless cars.
Listeners, start your engines. Before we start the story today, I want to ask you to imagine a different version of your life. You're you, but it's almost 200 years ago. And unfortunately, I don't have that call. It's Monday morning.
And it's very early. Pre-dawn. You wake up to this really hard wrapping at your window. That's the knocker-upper here to get you up for work. We're in the 1800s before the invention of the adjustable alarm clock.
The knocker-upper is a job. The knocker-upper walks the neighborhood with a long stick and taps it on the windows of people's houses early in the morning to wake them up for work. Who wakes up the knocker-upper for work? Nobody knows. But this is a job.
A job that'll actually exist for another century. Outside, the gas street lamps are still burning. The lamp lighter lit them the night before. He's supposed to come at dawn to extinguish them, but it's so early that he hasn't yet. The lamp lighter is one of those neighbors you have a deep fondness for, a fixture.
Every day you watch him make the rounds a desk with his ladder and his light. You, yourself, are a driver. Professional driver 200 years ago is also a job. You're a person who sits on a coach and holds the reins of a horse. You take passengers where they want to go.
You start your work day. Okay. Hypothetical over. Two of those jobs are obviously so long and disappeared that most people don't know about them. The knocker-upper is your iPhone alarm.
The lamp lighter is the electric streetlight. The third one, driver, has persisted. As a job for some, as a routine human task for nearly everyone else. This is a story about whether that's about to change. It's about how the word driver, which right now makes me picture a human, could soon transform to refer to a machine.
The same way the words dishwasher, printer, and computer all dead. I've thought about this maybe too much in the year I've been working on this story. In conversations constantly, I'd ask the human same question. Are you a good driver? Are you a serious public good driver?
I do. Within limits. I think I'm a good driver because I understand the limitations of my driving. This is Alex Davies. He wrote an excellent book called Driven, The Race to Create the Autonomous Car.
Alex, like me, thinks a lot about human driving. I've had his own personal limitations. What are the limitations? The limitations are that I can't always pay attention to everything, that I get tired. I've been trying really hard to be calmer on the road.
My husband and I are expecting our first baby this fall. Congratulations. Thank you. And I thought that along with reading all the baby books, a good project to work on is just be calmer in the car. A very good resolution because of course for most of us, driving is the riskiest behavior we routinely engage in.
In fact, even Alex, despite his good intentions, would actually get in a car accident just a few months after we first spoke. He was okay. It was the car that was totaled. Safety is the entire pitch for the driverless car, which is really a car driven by a computer. Driverless cars don't get drunk, tired, or distracted.
They never text or feel road rage. And these driverless cars, they aren't the future. They're actually already here. But it's funny, if you just don't happen to live in a place that already has them, it's easy to not see how fast things are changing. Road taxis, like Waymo, are operating in 10 American cities, providing millions of rides to Americans.
In China, the rollout is happening even more widely from twice as many cities. But here, if you live in a place like San Francisco or Austin, today a driverless car is about as exotic as an Uber. A passenger in those cities opens up their phone and decides who to drive them. A human driver or a robot driver. How that happened?
It's a story. A story we are living through right now, who's ending promises to totally reshape the places we live. And today we're going to tell you how we got here in chapters. Chapter one, dreams without drivers. So it turns out this dream that inventors have had to replace the human driver with some kind of machine, that dream is about as old as the lamp liners.
People have been thinking about a self-driving car for just about as long as there's been a human driven car. Why? There's this funny thing you lose when you move from the horse to the human driven car, which is that in a horse-drawn carriage, the horse is not just going to run off a cliff if you let go of the reins. You lose sentience in your vehicle. When automobiles first arrived, these powerful and non-sentient cars, there's actually a passionate fight to keep them off the streets.
It was the 1800s, and people feared these new things. The steam powered vehicles thundering down the roads that soon evolved into gas powered vehicles, also thundering down the roads. The fear was partly about jobs. These vehicles were seen as a huge threat to a whole network of working-class jobs. Horse breeders and horse barriers, horse feet suppliers, horse manure haulers, horse carriage manufacturers, not to mention the Teamsters.
Teamsters, today, the word makes me think of the Teamsters Union, but originally the Teamsters were the workers who drove teams of horses. Teamsters were like truckers before we had trucks. Cars seemed to imperil all these horse-related jobs. And even if you weren't worried about these workers, the cars were also less safe. Some anti-car activists battled to stop or slow the new technology, mainly with regulations.
There were red flag laws, which said if you had not a mobile, you had to hire a person to walk in front of it, waving a giant red flag to warn people. In Pennsylvania, a law was proposed requiring horse-less carriage drivers who encountered livestock to stop, disassembled their car, and hide the parts behind the bushups. The governor vetoed it. But the thing about these crazy anti-car activists is that, directionally, they were right. Those cars did initially wipe out a lot of jobs, even if they created more.
The cars were very unsafe. The cities that threw their doors open to cars without regulation were rewarded with astonishing death rates. Detroit led drivers pretty much run wild. In the early 1900s, deaths accumulated, and a Detroit without driver's licenses stoplights return signals. Many of those deaths were children.
It took decades for society to mostly learn to live with cars. The rest of the story is just the world you grew up in. We invented laws, licenses, drivers added. We learned to better design roads. We invented the highway, the seatbelt, the airbag.
All those things made driving less deadly, although the smartphone reversed some of that progress. And nationally today, deaths from cars are about as common in America as deaths from guns or opioids. We got one in 100. It'll probably happen to someone you know in your life. Maybe several someones.
Whether or not you see that as an urgent problem to solve depends on you. But as long as there have been cars, there have been people who wanted to truly solve what's left of the safety problem. The best way we knew how. They wanted to make the car more like the horse it replaced. Make the car more sentient.
So that thought is there early, and early visions of it include, oh well, we'll have radio-controlled cars because they had radios at the time. There's a real effort at one point to build magnets under the rope. And at each stage, what a self-driving car can be is dictated by the technology that's available at the time, for the most part. No one's thinking that much about a vehicle that thinks for itself. They're just thinking about a vehicle that the person in it doesn't have to drive.
Many different attempts, many different failures. As many wonders as we invented, we cannot approach nature's most majestic creation. A horse's brain. At least not until the turn of the millennium. Deep within the Department of Defense, there's a little no military agency that has created some of the most innovative technology of the 20th century.
This is the story of DARPA. Chapter two. DARPA's Million Dollar Prize. DARPA's current goal is to develop autonomous military vehicles, machines that can operate on their own without drivers. DARPA's always been intrigued with this.
This is from a documentary called The Million Dollar Challenge, honestly less a dock more an ad for DARPA than Pentagon's research arm. DARPA's mission is to try to keep American technology one generation ahead of everybody else. It doesn't always work, but DARPA has invented or funded a lot. GPS and the M16, the early internet and the predator drone. In 2002, DARPA decided to pursue the driverless car in a very unusual way.
The director of DARPA, the time a guy named Tony Tether, who had been a door-to-door salesman in his use, definitely has that flair in that way of thinking says, let's have a contest. Let's see who can put all of these ingredients that we've developed together into a proper self-driving car. His original ideas will drive him down the Las Vegas Strip. That fellas immediately next because it's insane. All right.
You would have to literally gridlock a huge American city so people could put robot cars on it. Exactly. So he says, okay, do you know what? We'll do it in the desert. We'll do it in the desert outside Las Vegas.
And anyone who wants to can make a team, build a self-driving car, bring it to the desert and we'll race them. The driver that DARPA wanted to replace was the American soldier. DARPA wanted a vehicle that could drive itself down roads that might be filled with hidden explosive devices. So in this moment, at the tail end of the dot-com boom, DARPA is trying to inspire tech to build something besides another website. DARPA's Tony Tether announces that the prize for whoever can win its grand challenge will be $1 million.
The rules were very open. There were literals that you couldn't have two vehicles communicating with one another, but you could build any kind of vehicle you wanted. You could have six wheels. It could be a truck. It could be a motorcycle.
It could be a tricycle. It just couldn't attack other vehicles. That was rolled out early on. Oh, was that a concern that people would just like sort of battle bot the thing? Or sometimes a vehicle would have like a little shredder that would take out somebody else's.
Someone asked in the first Q&A at this, they said, can we attack other vehicles? They said, no. And it's funny you bring up battle bots because a lot of teams who entered this had battle bots history. Interesting. They were used to building robots for interesting purposes.
And when they called wind of this, they said, we can do this. We can scrap together some money and this will just be fun. I'm going to tell you what happened in this robot race in the desert, not because I care so much about these early robot vehicles, but because I care a lot about the engineers who were making them. These would be the people who would later go on to lead development for the billion dollar companies creating today's driverless cars. And these people had very different views about how to get that technology ready, different values when it came to things like the acceptability of risking human life.
Abstract differences have become very concrete later on. It's the point where people would be charged with federal crimes. That's the future. But listening to this part of the story, what I listen for is how much of it can you detect already? How much of the difference is already present?
The first engineer I want you to pay attention to is a man named Chris Ermson. And way back in 2002, how did you end up being part of the DARPA grand challenge? It sounded like fun. Chris, these days, the CEO of a large tech company, back then a PhD student at Carnegie Mellon University. When he first got recruited for the race, he was out in the field observing a robot as it crept across the Atacama Desert, training for its future deployment on the surface of Mars.
My PhD advisor came down and was really excited about this DARPA grand challenge thing and the opportunity that you'd have a robot run across the desert at 50 miles an hour just sounded exciting, having spent the last couple of weeks walking behind a robot at very low speed. So Chris would join Carnegie Mellon's Red Team and help build a car called Sandstorm, a bright red Humvee with the top loft off, a plethora of futuristic sensors mounted to it, like scanners at crackpot would use to search for aliens. You can see Chris back in the documentary. He explains to the filmmaker at the time that the hard part of course isn't the vehicle, it's the driver. How do you even begin to teach a computer to operate a Humvee at all?
How does a computer make the steering wheel turn? How does a computer change the pressure on the brake and the throttle? Those are the issues that we're fighting through right now. Sandstorm represented the best entry from the contest's traditional academic crowd, but there's a different crowd there too, represented best by a man named Anthony Lewandowski. Can you tell me about Anthony Lewandowski?
Anthony Lewandowski, where'd I begin? So Anthony is like an entrepreneur. He's a really charming guy. He's six foot six. He's gangly.
He has all get down. He grew up mostly in Belgium because his mom was working for the EO. For high school, he moved to Marin to live with his dad and he's a hustler. My name is Anthony Lewandowski. I was a grad student at Berkeley.
Instead of continuing on to get finished by PhD, I decided it was much better to do the grand challenge. We asked Anthony for an interview. He didn't respond. But here he is in the footage from back then. Anthony did not have the engineering experience or resources of a team like Carnegie Mellon's Red Team, so he tried something very different.
A vehicle that had almost no chance of winning the race, but was also perfectly designed to stand out to get a lot of attention, maybe a job. The race is only self-driving motorcycle. It was named a ghost rider, a stubby little thing covered in stickers, with an antenna on the back and cameras on the front. There's a steering actuator on the top here which allows us to modify the steering angle. So basically, if you're driving, you start to fall to the left, you steer left.
That makes you turn to the left and then you get a triple acceleration that puts you back out to the right. And you're monitoring that in real time and making small adjustments and you stay balanced. The strobe light is on. The command from the tower is to move. Ladies and gentlemen, sandstorm.
The race happens on a Saturday in March of 2004. An autonomous vehicle traversing the desert with the goal of keeping our young military personnel out of harm's way. Ooh, yah! What happens the first time they tried to do this competition? The 2004 Grand Challenges and other hysterical disaster.
Disaster number one, Ghost Rider, the motorcycle. Anthony Lewandowski forgot to flip on the switch for the stabilization system. The bike immediately topples. Ghost Rider down. Anthony, good effort.
And then every vehicle after him fails miserably. Like one vehicle drives up onto a firm flips off. One vehicle drives straight out, does an inexplicable u-turn, and just drives back to the starting line. And the rules are that once your vehicle starts, you can't do anything. Even sandstorm got stuck on a firm.
Chris Ermson just standing there, unable to help his robot. Poor thing was trying to get going, but its wheels were just spinning on the gravel and tried so hard that it actually melted the rubber of the tires. And so it was just plumes of black smoke before they killed it. For the robot, this was obviously very disappointing. Chris Ermson compared it to an Olympic marathon where the best runner only makes it too.
What this contest had done was it had flushed all these adventures out. It had jumped started the scene that would develop this technology. One of the most important people there that day, actually just watching, was someone I haven't mentioned yet. A legendary roboticist named Sebastian Thrun. Sebastian Thrun, he was at the first Grand Challenge.
He didn't bring a team, he wasn't participating. Gabriel wanted to show off some other projects. He'd been funding, including one of his robots, so he brings the robot. So he's there. And he watches this disaster, and he thinks, I can do better than this.
I looked at the very first iteration of this Grand Challenge, but I didn't participate. I was a spectator. This, of course, Sebastian Thrun. He grew up in West Germany, moved to the US, taught at Carnegie Mellon before moving to Stanford. Watching that day, he saw this fundamental error he believed all the entrants had made.
I saw that all the teams tweeted this like a hardware problem. They looked at this and said, we have to be able to grow a bigger wheeler, a little bit bigger chassis and so on. And I looked at this and said about, wait a minute, the challenge really is to build a self-driving car that can drive for the desert. I can get a rental car, they can do it just fine, provide there's a person inside. And the challenge is to take the person out of the driver's seat and replace a big computer.
That is not a problem of bigger tires. Sebastian Thrun had a dual background, robotics and artificial intelligence, which probably explains his focus here on the robot driver's mind. He was thinking about something else, too. The military wanted this tech to replace a relatively small number of drivers in its war zones. But Sebastian was already imagining something bigger.
What would happen to traffic deaths worldwide if one day everyone had access to a driverless car? I had experiences of losing people in my life to traffic accidents and I felt we lost over the million people in the world to traffic accidents. Wouldn't it be amazing if Dubbov invented something that would save a million lives here? In October of 2005, 43 teams have brought their vehicles to compete in a unique event, a race driven not by testosterone but computer code. Chapter 3.
Machine. Learning. The race course is a circular maze that zigzags for 132 hours. 18 months later, for the second grand challenge, Dubbov doubled the belly, $2 million. This footage is from a PBS documentary called The Great Robot Race, narrated to my mild joy by John Liscow.
Familiar faces have returned. Chris Rumsen, back with the Carnegie Mellon team, designed with two vehicles, Highlander and Sandstorm. The Antony 11 Dowsky, back with his motorcycle, which still doesn't work, is knocked down the qualifiers. And now, there's also Stanford's entrance. Compared to Sandstorm, the bulked up Hummer, the car looks amisily, a blue SUV donated by Volkswagen, a baby faced with a run and smiles next to his soccer mom looking vehicle.
The vehicle's name is Stanley, so Stanley is nothing else but Stanford. But it also gives the vehicle a personality. We think of the vehicle more and more as an intelligent decision maker. And Thrun really brought more artificial intelligence, which at the time we're talking about, we're still rather primitive, especially compared to what we have today. But he could use it to teach his vehicle how to recognize the road and how to do it much faster.
They found a dirt road out near Stanford and they drive it down a dirt road and have the car's caras record what they were seeing. The robot Stanley was able to train itself as it went. And the way it worked is his eyes looked way ahead and it could see stuff way at distance. When it dries up and it was a good place to drive it out because it could measure how slippery or how bumpy the road was. And they could then retroactively train and say, this green stuff over there, it's something a good drive on, aka grass.
And this brown stuff, aka mud, is not so good to drive. And so it was able to detect patterns and generalize from what it had learned. Yeah, absolutely. And it did this like 30 times a second. I mean, just like a person.
The race kicks off with Stanley sandwiched between Carnegie Mellon's two behemoths. Highlander leads the pack followed by Stanley and Sandstorm. What happens in the second race? The second race is as successful as the first race is disastrous. Nearly every entry in the second race would go further than Sandstorm had the first.
Multiple vehicles would finish the course. The real question was who would do it fastest? And so at one point was it clear to you that you were going to win. Well, once we passed the front running team, we kind of saw the vehicle descend into a hard spot of the race course, a very, very treachery mountain pass. And we saw at a distance a dust cloud, we saw a helicopter.
We saw little features that made us believe, wow, there's something happening that's magical. And this dust cloud then all of a sudden turned bluish because the car was blue and came closer. And then it came first to the finish line. It was unbelievable magical. At the end of the dock over some criminally corny piano music.
Sebastian Thron gives his post-race interview. He's dressed a lot like a race car driver, watching you could forget he wasn't in the car. It was just amazing to see this community of people. That community succeeded today. Behind me there were three robots that made all the way through the desert.
And all of them did the unthinkable. It's such a fantastic success for this community. I think we all win. I made for TV Kumbai Amamamam. Still years before the race to build driverless cars would enter its cutthroat phase.
What would happen next is that a small band of lunatics would take driverless cars out of the desert, start secretly driving them on public roads in the state of California. They would do this at the behest of a man who'd been observing from the stand set day, disguised in a hat and sunglasses who'd watched the challenge. It was mine spun. It's after a short break. I'm Stephen Dubner and you are listening to a special episode of the podcast Search Engine here on Freakonomics Radio.
We will be right back. It's Stephen Dubner. Today we are running an episode from the Search Engine Podcast with host PJ Vaux. Chapter four. Something actually useful for the world.
The race in the desert had been designed as a spectacle. Something flashy to dry out America's smartest robot assets. But it had drawn another person who come for his own reasons. Google's Larry Page arrived at the DARPA Grand Challenge in a baseball hat and sunglasses in disguise. He found Sebastian Thrun and button-holding, asking him a million highly specific questions about things like the wavelength his LIDAR system used.
But this meeting in the desert, this was not actually their first introduction. Well, the first time I met Larry was a bit earlier. He had built a small little robot that acted as a telepresence for meetings. And he was trying to drive around the Google offices instead of himself going to meet with the robot. And he sent me a message and said, I'm going to show you the robot I've built.
And in a spur of craziness, I send a message back saying, Larry, I'm so glad that Google had to use 20% of the time. It was something useful for the world. I couldn't have it. I either expected a rapid response or never hear from him again. It turns out I was lucky he responded immediately.
I took his robot, I fixed it next 24 hours, and he was very heavy. Larry Page turned out and actually been interested in autonomous vehicles since at least grad school. That's what he'd wanted to do his thesis on before being guided by some wise PhD advisor towards search engines instead. Now, as a spectator at DARPA's second grand challenge, he'd see real-world evidence that autonomous vehicles might actually be a thing. At first, Larry Page hires Sebastian Thrun along with fellow DARPA contestants Anthony Lewandowski just to build what will become Google's Street View.
They'll actually modify the system that Stanley the Car's roof-mounted cameras had used to begin photographing American streets. But before long, Larry Page returns to Sebastian with his dream of a driverless car. And so how soon after arriving at Google, this project chauffeur began. Like Larry Page says to you, I have a mission? Like, how does this happen?
This is an embarrassing moment for me. It's about two years later, 2009, who has seen my cubicle, and Larry Page comes by and says Sebastian, I think you should pay the self-tapping car. They can drive anywhere in the world. And my immediate reaction was, no, taking the technology to be paid for this empty desert and putting it in the middle of a market street in San Francisco is going to kill somebody. And Larry would come back the next day with the same idea, and I would give him the same answer.
And both of us got increasingly frustrated. Like, damn it, it can't be done. And eventually it came and said, look Sebastian, okay, I'll get it. You can't do it. I want to explain to Eric Schmidt, the CEO at the time, and Sergey Brane, my co-founder, why it can't be done.
Can you give me the technical reason why it can't be done? And that's the moment of incredible pain, because I go home and I can't think of a technical reason why not. It was this moment where I felt, look, I'm the world expert in self-tapping cars. And I'm the person who denies that it can't be done. That taught me an incredibly important lesson about experts.
That for the rest of my life, I decided experts, actually, actually the past month of the future. And if you ask an expert about innovation, something crazy new, there's at least likely person to say, yes, they came me down. So this is where the Google self-driving car project begins in 2009. It's led by Sebastian, joined by others from the DARPA challenges. The methodical Chris Armsen was running most things day to day.
Anthony Lewandowski, the flashy motorcycle guy, would work on hardware. Dimitri Doga, another DARPA veteran, would be responsible for planning and optimization. It was a secret project. They'd report directly to Larry Page, a small enough team that there'd be no bureaucracy, few emails, fewer meetings. Just 11 engineers who writer Alex Davies says represented some of the best young talent in the country.
And so Google builds this very quiet team, and it says to them, build us a self-driving car. And because that goal is super nebulous, they give them two challenges. They say, safely log 100,000 miles on public roads, but they also give them a challenge called the Larry 1K. So Larry and Sergey and I set together, and the two of them carved out a thousand total miles of road surface in California. They open up Google Maps, and they just click around and they look for 10 separate 100-mile routes that are really tricky.
Apps, everything, like the Bay Bridge and Lake Tahoe and Highway 1, Toulas Angeles and Market Street and even Crooked Loma Street. And they say to the team, you have to drive each of these 100-mile routes without one human takeover of the system, without one failure of the car. To get off to a running start, the team licenses the code from Stanford's DARPA Urban Challenge Vehicle. Anthony Lewandowski goes to a local Toyota dealership and buys eight Priuses, takes them back to Google, and retrofits them to accept a computer as a driver. He hooks that computer driver electronically into the brakes, the gas, the steering.
These Priuses get a radar system behind the bumper, cameras, a lidar system, spinning 360 degrees on top. Lidar, like radar, but it shoots lasers instead of radio waves. At first, the team gives each Prius a cool name, like Night Rider. But I think we quickly realized that we're not going to be able to name all these vehicles as we scale up our fleet, and so we just started to number them, like Prius 27. This is Don Burnett. He'd been a researcher working on autonomous submarines.
He also found in a car accident, separately gotten a bad accident himself, and decided that he wanted to do work on self-driving cars. That's how he eventually ended up on the team in its early days. I was on the motion planning and behavior decision-making team, and my responsibility was to work on the nudging behavior. Nudging would a big truck pass as a human driver on the right. The driver would nudge a little to the left.
For us, it's an instinct. Don's job was to teach a computer to nudge. I tried to encode the behavior that you would use as a driver under partially good perception. And it's a really tricky problem. A team of academic roboticists, some of whom had had friends, not in cars, spending Google's money to see if they could make driving safer.
It was a weird era. There's this big concert on your Google's offices called the Shoreline Amphitheater. In 2009, you could have seen Cheryl Crow there, the killers, fish. But the most interesting show that year was one nobody knew about. In the venue parking lot, on days when there was no concert, no tour buses around to see them.
The Google team would run its first test runs of their driverless cars, essentially hiding in plain sight. A Prius driving itself around the amphitheater parking lot with an attentive safety driver sitting behind the wheel, just in case. The team was making sure the basics functioned, that the sensors could recognize another car, that the computer in the car was abiding by their orders. These were the baby steps. They'd happen in this parking lot and at an empty airplane runway, as close to their offices.
Spring 2009, the team tries actual real road driving for the first time. Chris Ermson takes one of the Prius' out on the central expressway. Speed limit, 45 miles per hour. There are humans driving here. And immediately, outside the confines of the empty parking lot and empty airplane runway, here's what's clear.
They had a real problem. The car was swerving wildly. It was weaving around like a drunken sailor. And we realized that the scale of the runway was such that you didn't notice the one or two foot kind of oscillation it had in lateral control. And you put it on central expressway and suddenly, yep, turns out actually that's a problem.
One more problem to fix. Listening to the story, it's funny because I can imagine it getting me a totally different feeling than it does. A tech company, with nobody's permission, was testing driverless cars on public roads in California. I don't know why that strikes me as being about invention, instead of just hubris and impunity. Maybe it's because I know that Google would be one of the few tech companies whose driverless cars would not cause any fatal accidents in testing.
And that the team would just take more safety precautions than the other companies who'd rush in later to catch up with them once this was an arms race. The way these cars were designed, the safety drivers at behind the steering wheel, ready to take over. In the other seat was their partner, watching the monitor displaying a graphical interface, designed by a Dmitry Dolgov. The people watching the screen would call out problems ahead, some discrepancy between what the sensors were seeing and what was actually in the road. This is what teaching a car to drive actually looked like.
Two-person team is manning the cars, logging errors, going back to the office to troubleshoot and then updating the code. I asked Don Bernad about this era. And while you're doing this and then you leave work and you get in your car, that you drive as a human, did you find yourself thinking more carefully like, how do I know what I know when I'm driving? Like you're trying to teach a machine by day. Did it affect how you thought about human driving by night?
Almost obnoxiously so to any passengers in the car with me. I was obsessed with one big question, which is why do humans drive the way they drive? And it turns out there were no good answers. And I still think there are not great answers. And instead of actually answering that question, we just turn to machine learning to infer the deep truths behind why humans do what they do.
And so there's some basic principles that you can understand. Like we try to minimize lateral acceleration, meaning you don't want to be thrown to the outside of your car when you're making a turn. So you're going to slow down. But how much do you slow down, right? And it turns out that's contextual.
Don gave me an example. So you're trying to figure out the right speed and angle for the car on one of those tight curvy on ramps onto the highway. You want it to feel comfortable for a passenger. Don says you can work out the math that lateral acceleration is two meters per second squared. But the surprising thing is that number only applies on the on ramp.
If I put you at a cul-de-sac in a neighborhood and you were going to do a U-turn at the end of the cul-de-sac, even though the speed is significantly slower, if you did two meters per second squared of lateral acceleration around a cul-de-sac, you would tell your driver they were crazy. It would look incredibly uncomfortable. Like incredibly uncomfortable. You would feel like you were in Mario Kart. Yes, it would feel Mario Kart. And remember, this is a force.
So it's a physical feeling on your body is exactly the same, but the contextual awareness of the situation of speeding up to get on the highway versus making a U-turn in a residential street tricks your brain into feeling opposite about the situation. And so it turns out the limit for a cul-de-sac is around .75. It's almost three times less than you would be willing to tolerate as you accelerate onto a highway. And so there were things like that where you couldn't just say humans have specific physical restrictions, right from a forces perspective. The context matters.
And when the context matters, now all of a sudden anything is game. So things like that is where I spent my time as a researcher trying to figure out, okay, how are we going to make this comfortable for passengers? All these little problems to solve. But there's one gift, which is that the team at this point had an overarching goal uniting them. The DARPA talent had told them, drive across this Valeriy when K Challenge told them, drive these 10 routes without human intervention.
The specificity of the mission meant they never had to squabble about why they were there. By 2010, just a year in, the team was really on a roll. They start knocking out routes. Each one of the routes was unique and distinct and different, and had its own challenges. Down Route 1, Silicon Valley to Carmel.
The bridges run. We had to go across all the bridges in the Bay Area, starting in Mountain View, finishing, crossing the Golden Gate Bridge. It's Chris Hermsen in the car, Anthony Lewandowski in the car. I was in the car with Dimitri, Chris, and Anthony. It was the four of us in the Prius.
They were figuring out the technology much faster than they thought they could. The Larry 1K was set up like a video game, meaning they get to try the route over and over until they could complete it without a single human takeover. Then they move on to the next one. It was really a proof of concept exercise. Can you even make this happen once?
When they fail a route, they know what the car can't handle, so they go back and say, they have to be better at doing XYZ. And then we got back to the office. We regrouped. We went back out, I think, at like 11 p.m. And by 1 a.m. we had completed the route. They buy a bottle of
Corbel champagne. They all write their names on it. Corbel, 1399 a bottle. The champagne they have a traitor Joe's. They had won for every route they completed. And one by one they pick off the Larry
1K routes and they think this is going to take them about two years when they start out and they do it in a little bit more than a year, nearly twice as fast as they had expected. By fall of 2010, they're done. Here's Chris Hermsen. And I think we had a big party up at Bastion's House in Los Santos Hills. So it was pretty spectacular, right? They throw each other in the pool. They celebrate.
And then they're not entirely sure what to do next. It was kind of a okay and now what? The team had pulled off a kind of miracle in a year. A driverless car with human supervision, with a loss of human coding. But still, a driverless car successfully navigating some very tricky roads in California. They've done this safely, they've done it quickly. And now things would begin to
wobble. Competition would arrive. The team itself would begin to skis them. And one member, a person who believed the team was moving too slowly, would actually take matters into his own hands in a particularly extreme way. After the break. Hey there, Stephen Dubner. That again is PJ
Vote. And you are listening to an episode of the Search Engine Podcast here on Freaking Comics Radio. We will be right back. Welcome back to the show. As early as 2010, Google's driverless car project had developed some very impressive self-driving technology. But what
they were struggling to decide was this. What was the actual product they were developing here? Here's Bastion Thrun. We had a lot of debates inside Google. What the business model was.
At some point, we actually had a big debate. We should just buy Tesla. And Tesla was worth $2 billion at the time. I remember this. Maybe you should have an hindsight. But joking aside,
there was a debate whether this is more of an assistive technology or a disruptive replacement technology. Basically, should they follow the route that Tesla ultimately would design self-driving as a feature in your car, something that could take over sometimes but still need human monitoring? Or was it better to wait until the car could fully drive itself? Thrun would eventually come around to this version of self-driving. Specifically, he'd come around to the idea of self-driving robo taxis. A taxi service type system is way more capital efficient than ownership. An owned car is being
used about 4% of the time. And it's a park, 96.5. And imagine a city without park cars. Where every car is being utilized for its 50% of the time. Which means we have only 10% of the number of cars needed that we need today when we own cars. That's going to happen. There's no
absolute question. What's the bastion is describing here so matter of factually is a fairly radical reimagination of American cities. The idea that robo taxis would be so cheap and widely available that most people just wouldn't own cars, that we could put something else, anything else, in the places where we put most of our parking lots and parking spaces, that is a far-fetched idea. Just given how much of American identity is tied into personal car ownership. A far-fetched idea, and for it to begin to happen, Google would have to bring a product to market. But the years passed,
and they didn't. And some people who were there felt stuck. Don Burnett says he believes life at Google got dangerously cushy. The food was great, the money was too. These former academics making much more than they never expected. There was a lack of urgency on the team to actually make something
viable. We had a funding supply that effectively felt infinite. And maybe it wasn't. But it certainly felt infinite. And when you have infinite funding, you're not forced to make hard decisions. You're
not forced to focus. You're not forced to look at the opportunity, the market, the customer, and be the best. It was more like, hey, let's take our time. Let's make sure we do it right, which is on its face a good principle. But at the end of the day, I think the lack of urgency wasn't for everyone. And within the team, you've got team Chris and team Anthony. And they start butting heads
all the time. Chris and Anthony, meaning Chris Armsen, official head of the project, versus Anthony Lewandowski, who I still think of as the motorcycle guy. The main difference in their approach is how quickly they want to move. Anthony is very okay with risk, we'll say. He gets one of these cars and he's driving it back and he lives in Berkeley, works in Palo Alto. He's just using this car on the
Bay Bridge every day, probably outside the bounds of what the team actually wanted. And he's not necessarily logging data. He's just enjoying his self-driving car. Taking it all over the place, Chris comes from an academic background. He's that Canadian, very nice, very careful, very risk-averse.
When I asked Chris Armsen about all this, his memory was slightly different. In his memory, Team Anthony was pretty much just Anthony. And Anthony, he said, was a move fast and break things kind of guy. Move fast and break things. A motto famously coined by Mark Zuckerberg. It defines a
way of developing technology which once might have felt cute and revolutionary, but which today, at least to me, feels pre-responsible. Chris didn't think that philosophy was an option for their team. Even if their cars were statistically safer than human drivers, he knew that the first news story about a self-driving car in a fatal accident was going to be a huge deal. An anecdote was going to demolish data if they weren't extremely careful. By all accounts, Anthony Lewandowski felt differently. But he actually wasn't the only one. Here's Don Bernat.
There were some people on the team, very famously, including myself, that started to get the itch kind of towards a three to four year mark. The itch of like, okay, where is this going? Who is it for? How are they going to use it? Where are they going to use it? And I felt like the leadership didn't
have great answers to that. There was no commercial race, right? We had no competition and there was no market for the product. But competition would soon arrive in the form of Uber. This was the oh shit moment for me. Uber announced their self-driving program. And I remember, like it was yesterday, waking
up, reading the news, going to my desk in the morning and thinking, oh crap, these guys are going to eat our lunch. In 2013, then CEO of Uber, Travis Kalenak, had gotten a ride in one of Google's prototype driverless cars. Sitting in a taxi without a human driver, he'd understood that this could be the end of this company. And so Uber had plunged headlong into the driverless car race. The company hired nearly half of Carnegie Mellon's top robotics lab. And not long after,
we also know through court records and emails that Uber also began communicating with Anthony Lewandowski, who in 2016 would leave Google, quitting just before he could be fired but recruiting team members away, including Don Burnett. Anthony would then start his own autonomous vehicle company, Uber would soon buy that company for almost $700 million. Even though the company had no product and was only months old, which raised the mystery, why would Uber pay so much for a company whose only assets seem to be its people? This is where Google goes into its computer security logs and realizes that not long before he left, Anthony Lewandowski downloaded something like 14,000 technical files onto his computer and moved them onto an external disk. Obviously, you can't do that. I mean,
I'm assuming obviously you can't do that. No, you definitely cannot. And that's the kind of thing that maybe if he had stayed there, this is the kind of thing Anthony would have done, anyone would have been like, oh, it's just so I could have access it to it somewhere else. They probably would have gotten away with it. But when you then go and work for Uber and start running their direct competitor self-driving car program, that's when you get in trouble. And that's when what's technically called Waymo at this point, Google's program
inputs Anthony at the center of an enormous legal battle between these tech giants. Secrets and subterfuge in Silicon Valley, a former Google engineer, has been charged with stealing files from Alphabet's self-driving car project and taking them to Uber. Specifically, it involves a former lead engineer of Google's self-driving car unit Anthony Lewandowski. Now, he's accused of using his personal laptop and downloading more than 14,000. In 2016, Google had just spun its driverless car unit into a new entity, Waymo. Waymo sued Uber. Uber had to settle to the tune of
$245 million. And in a separate criminal trial, Anthony Lewandowski pled guilty to stealing trade secrets. Afterwards, Uber continues their driverless car program without him, continuing to pursue its move fast, break things strategy, which in 2018 leads to the death of a woman named Elaine Hertzberg. Uber is setting the brakes on its self-driving cars after one of them hit and killed a woman in Arizona. The vehicle was in autonomous mode, but it did have a safety driver on board. But a police
report later indicating the safety driver was streaming TV shows on her phone for three hours that night, including at the time of the crash. The way the story was reported, nearly everyone blames the safety driver. She was on her phone. She was streaming an episode of the voice. Tempe investigators saying Hadvask has been paying attention to the road, she could have stopped the car 42 feet before impact. The NTSB slamming Uber on the vehicle.
There was some important additional context, which was that Uber's robot driver was also just much worse than Waymo's. A statistic I found dropping, at this point, Waymo's safety drivers were having to take over from the car once every 5,600 miles. Uber's safety driver's that year had intervened more than once every 13 miles. Despite that, five months before the crash, over employee objections, Uber had cut its safety crews. Instead of two humans, they just used one.
One safety driver overseeing a robot driver that was arguably not ready to be on public roads. In the last moments of Lane Hertzberg's life, the robot spent an indefensible 5.6 seconds trying and failing to guess the shape in the road that was a human body pushing a bike. Over those 5.6 seconds, the robot kept reclassifying her, wishing her no-no object, a vehicle, a bicycle. During that time spent wondering, the car did not slow down. Soon after Lane Hertzberg's death, Uber halted its testing program. Uber has temporarily suspended its driverless fleet nationwide as the NTSB,
police, Uber, and the National Highway Traffic Safety Administration investigate. We reached out to Uber for comment. A spokesperson said that the fatal collision was indeed a tragedy, which had a significant impact on Uber and the entire industry. There would be other competitors, who would shut down after similar accidents. There would also be Tesla, which by 2020 was publicly marketing a product company called full self-driving, but which absolutely was not. Meanwhile,
Waymo had slowly continued to develop its tech. Their robot taxis would be ready for riders by 2020. The team had gotten an unexpected boost from a technology that was, at the time, very little understood. In 2026, when most people talk about artificial intelligence, the conversation defaults to products like chat, GBT, and cloud. But artificial intelligence has been a core part of driverless cars going back two decades. In the 2010s, neural net advances meant that you can
now begin to feed a computer system, large amounts of data, and watch as its perception, prediction, and decision-making abilities improved. Here's Sebastian Thrun. That technology of massive data training was made us want to get go, but it's become more and more and more important. The surprise for all of us has been that size matters. When you put a million documents into an AI, it's fine. A hundred million is fine. If you put a hundred billion
documents into an AI, it is unbelievably smart. And that I think shocked everybody myself into it. The Google Brain team, the deep learning people, started working with the driverless car team to use training data to help the computer driver learn things, like how to better predict when another car was about to suddenly switch lanes, how to more reliably spot pedestrians. Over the years, as the car drove more miles, as the team gathered more data, plugged that data into their AI systems and tweaked those systems, the engineers say the robot driver kept improving. As they tested the car in new weather conditions, they discovered problems that required hardware fixes. For instance, in Phoenix, Waymo had to design miniature wipers for their cars
lye-dars sensors to deal with the desk storms and heavy rains. In 2020, Waymo finally debuted to the public in Arizona. In the years after, it'll roll out to 10 more American cities. A funny consequence of Waymo's long development cycle is that the public's attitude towards Silicon Valley has just really changed in that time. There's more suspicion for Google than there was back in 2009 when the project first started. And so now, many people look at the Waymo driver with a
raised eyebrow with a question immediately on their lips. Chapter 5. Are you a good driver? All right, autonomous vehicles can now get you around Atlanta yesterday. A fleet of white electric jaguars covered in 40 different sensors, cameras, radar, LiDAR. It's an expensive car, as much as $150,000 by some estimates. In a news story, you see the
inside where the human driver would normally set. There's an empty seat. You're not allowed in. With a steering wheel in front of it, pistigial, it turns itself. Cars without drivers are here.
Yeah, sounds like something out of the Jetsons, but get ready because you may look over at the car next to you and see it rolling down the street. The TV news has always used the same G-Wiz tone. They never resist the Jetsons' reference. In every city, the influencers happen to record testimonials for their daily serving of clout. So in today's video, I'm about to take my first ever driverless car. It's with an app called Waymo. Waymo is basically driverless car Uber, where
like ride service, you call it, go wherever you need it to go, but there's no driver. You guys, this is creepy. It's like I'm being driven around by a ghost person. It's a little terrifying. Robotaxis, poll hilariously badly. According to J.D. Power, a data analytics firm, among people who've
not ridden in one, consumer confidence is at 20%. But among people who have taken a ride, it never shoots up to 76%. It's a thing I didn't capture in the story, but when I said one a couple years ago, I just found it persuasive as an experience. You know what? I'm not as nervous as I thought I was going to be. This is actually quite relaxing. My schedule turned, felt very safe. You know, it
was kind of freaky at first, but now it's pretty chill. Smooth ride though. They went drive fast. They went jerking. It's driving like you always hope your Uber driver would. So I guess that's one of the big
cell phones that the Mythological team leader had left Google years ago. But he told me about his experience as a civilian consumer, trying Waymo out in the world. My universal experience has been, and you can tell me if this was your experience, the first couple of minutes in the vehicle, it's, huh, that's crazy. There's nobody behind the wheel. It's from the sharks. And then a few
minutes in, it's like, okay, you know, it's just going to drive. Is that all it does? And then, you know, 10 minutes and people are looking at their phone. People tend to feel safe in these cars, but are they actually? So we know that the Waymo driver has now driven over 200 million real-world miles. And they released safety data so far for the first 127 million miles. Waymo's fairly
transparent. They released their crash and safety data, un-redacted to the public. By contrast, Tesla redacts the details of scratches. The company says they are confidential business information. In Waymo's case, I've looked at the data. I've looked at how the company interprets
it, how skeptical independent researchers interpret it. I wanted to walk through it with an autonomous vehicle reporter I trust. His name is Timothy Bealy, author of the newsletter, Understanding AI. I asked him how much our picture of the Waymo safety data has been evolving. So it's been pretty consistent the last couple of years. They are scaling up. And so all the numbers get bigger,
like the total number of miles get bigger than the number of crashes get bigger, but the like crashes per mile have not changed a ton. Waymo says, and I think this is correct, that it's roughly 80% safer in terms of crashes that are severe enough to trigger an airbag, crashes that are very enough to cause an injury, and also crashes involving vulnerable road users like pedestrians or bicyclists. So 80% fewer airbag crashes than human drivers, and actually 90% fewer crashes that cause a serious injury. Some independent experts have small quibbles with methodology, but broadly they find Waymo's data credible. Timothy pointed out there's one very important thing we don't know, the fatal crash comparison. For every 100 million miles humans
drive, we cause a little over one fatal crash. The Waymo driver has driven 200 million miles without causing a fatal crash, but statistically speaking, that can still be a fluke. Some academics have suggested we need about 300 million miles to have statistical confidence. In the hundreds of millions of miles the Waymo driver has traveled. It was involved in two fatal crashes, which it did not appear to cause. Here are the details of those crashes. In one, a speeding human driver rear-ended
a line of vehicles at a stoplight. There's an empty Waymo in the line of struck cars. In another crash, a Waymo was yielding for a pedestrian. It was rear-ended by a motorcycle. The motorcycle driver was then struck by a second car. That's everything. When Timothy B. Lee looks at the entire safety
picture, the results we have so far from this big experiment Waymo is conducting on American roads, what he sees is mainly promising. So far, it's better than human drivers and so far, I think the case for a lot of the victim to do the experiment is very strong. Which doesn't mean we shouldn't scrutinize this Waymo experiment as it continues. I find myself paying a lot of attention to Waymo crashes, which isn't hard. They make headlines. The most harrowing one recently was this January.
A child near the elementary school in Santa Monica is struck by a Waymo. A child ran across the street from behind a double-part car and a Waymo hit the kid. Santa Monica, please say the child, a ten-year-old girl was not hurt. The company issued a statement. Waymo said its driver had branked hard, reducing speed from 17 to under 6 mph. A faster reaction they claimed than a human driver would have been capable of.
What happened next at the accident scene actually answered a question I'd had. What does a Waymo do after a car crash since there's no human driver to help? Waymo employs what they call human fleet response agents, human beings who can't remotely drive the cars, but who the car can ask questions to if it gets confused. In Santa Monica, the Waymo called one of those humans, the human called 911, and this is the strangest part of Waymo's statement. Apparently, the car then waited at the scene of the accident until the police dismissed it. That's what we know so far, but there's two federal
agencies investigating this crash, and so we'll have a full report in the future. One problem that's not really captured in the safety data that I've seen is what I call troubling edge cases. You see them in videos on social media. A Waymo gets stuck at a dead stoplight, or a black emergency vehicle, or an example Timothy gave, Waymo's were driving past stopped school buses in Austin. I think it's reasonable to say, this is like a clear cut rule, that the vehicle should call this rule. These entities are still very rare, and so if it's a one-in-ten million thing,
I think it's not that big deal as long as they're in progress, which for most of these type of they are. Timothy pointed to one area where Waymo's not been as transparent as he'd like. Those human response agents, some of which are based here, some of the Philippines. There's questions about what specifically they do, and about how this will all work as Waymo scales up. We asked Waymo for comment on everything you heard in this episode, especially the recent safety incidents. A spokesperson said that the data to date indicates that the Waymo driver is already
making roads safer in the places where they operate and says that Waymo can use to work with policymakers and regulators to improve its technology. That's the safety picture so far, which to me, after many months of looking at this and talking to experts, looks pretty good. As Waymo continues its rollout, other companies are quickly falling behind. Amazon's new driverless taxi is launching in Las Vegas this summer, and it's expected to arrive in El Cusco. There's other road-attaxing companies like Amazon Uber is back in the mix, not making technology, but partnering with these road-attaxing companies.
We ride recently struck a partnership with Uber to bring its A-neas to Abu Dhabi, another sign of the car. And many other early Waymo engineers are now CEOs of autonomous companies themselves. The B-Tru Doga is actually co-CEO at Waymo, but other team members run driverless trucking companies. Don Burnett, founder and CEO of Kodiak A-I. Don, thank you so much for joining us.
It's good to see you again. Don Burnett is head of Kodiak A-I, which has a technology deployed in driverless trucks in the Permian Basin. Please welcome CEO of Aurora, Chris Ermsen, a big round of applause. Chris Ermsen now heads Aurora, which currently has semi-trucks on Texas highways. And my personal favorite plot development, which just emerged this week.
I just broke on the information that Uber founder Travis Kalanet is starting a new self-driving car company with financial backing from Uber and in partnership with Anthony Lewandowski. Now for those who've been following- They say there's no second acts in American lives. Somehow both of these men seem to be on their fourth. The big picture though is that everywhere in America today that you see a driver, taxi, truck, food delivery. There are several companies working on the robot version.
Trying their best to make driver as a job, start to go the way of the knocker-upper of the lamp-lighter. Those knocker-upper by the way, they disappeared quietly. The lamp-lighters did not. Redder Carl Benedict Frey tells the story of the lamp-lighters union. Heather strikes Paul and his New York City briefly into darkness, to the delight of lovers and thieves.
In Vervea Belgium, the lamp-lighters' strikes turned violent, ending an attack on the local police headquarters. The army was brought in. The lamp-lighters lost their fight, in part just because they were so outnumbered. But the drivers today fighting to save their livelihoods are a significantly bigger force. Please stand up, everybody that's right chair, union members or someone who drives a vehicle.
Stand up. 4.8 million Americans drive for living. It's one of the most common jobs we have. And these workers do not plan to surrender to the California tech companies. They're doing this because they stand to make an unfathomable amount of money if they eliminate driving jobs for working-class people. I understand it is business. It is capitalism.
But not in my city, at the expense of our jobs. These drivers are represented by unions backed by politicians, ending cities across America, blue cities. They're organizing. So far, they're winning. Humans drive the city, law machines, labor drives the city, keep the workers in the workforce.
If it works in another city, great. Have fun. Not yet. Not Boston. Thank you.
Next week, the fight to save a job. To save the human driver. Don't miss this one. I think I really had a sense of normal technological awe.
