Professor William Riggs on why we fear Waymos more than bad drivers

William Riggs is a professor of engineering and management at the University of San Francisco and an expert on transportation innovation. He says San Francisco — now ground zero for America's autonomous vehicle future, with more than 1,000 Waymos on its streets — is exposing a strange contradiction: Society tolerates the deadly carnage caused by human drivers while holding self-driving cars to an impossible standard, even as the data increasingly suggests the technology will save lives.
