Bob McMurray: Motorsport expert previews the Miami Grand Prix, discusses the regulation tweaks

Formula 1 is back in business this weekend.  The Miami Grand Prix follows a month-long break due to the conflict in the Middle East – both the Bahrain and Saudi races getting shelved.   Tweaks to the controversial new regulations and car upgrades will also be in play at the race.  Motorsport Expert Bob McMurray told Mike Hosking Miami is pivotal for the very future of Formula 1.  He says that if everything works well, they’ll continue quite happily, but if things continue as they have in previous Grands Prix, the organisation has a real problem as they can’t keep tweaking these regulations.   LISTEN ABOVE  See omnystudio.com/listener for privacy information.
