California often serves as a “canary in the coal mine for the country and the developed world,” said David Zipper, Visiting Fellow at the Harvard Kennedy School’s Taubman Center for State and Local Government.

The California Public Utilities Commission approved the permits for Waymo and Cruise on Thursday despite pushback from local leaders and many residents in San Francisco, who argue that the autonomous vehicles have caused chaos around the city — from traffic jams to disrupted emergency scenes.

But critics say this data is unreliable and incomplete because the companies are not required to report a range of other incidents that affect the public — such as when a car veers into a bike or bus lane or stops short and disrupts traffic.

Philip Koopman, a Carnegie Mellon University professor who has conducted research on autonomous-vehicle safety for decades, said the self-driving car companies are under intense pressure to turn a profit and — in some cases — prove the business’s viability to shareholders.

In Los Angeles, Jarvis Murray, the county’s transportation administrator, said it is “untenable” to allow a new mobility service to expand without requiring companies to report more data and also give the cities more say over what is happening on their public roadways.

In an attempt to halt Thursday’s vote, they wrote letters and spoke at hearings to bring attention to a string of incidents in recent months: A car stopping near the scene of a mass shooting, another getting tangled in caution tape and downed wires after a major storm and another blocking a firetruck from exiting a station for several minutes.
