SF Supervisor Bilal Mahmood launches inquiry into Waymo's July 4 traffic meltdown

On July 7, 2026, San Francisco Supervisor Bilal Mahmood announced a letter of inquiry to the city's Department of Emergency Management, Fire Department, and Municipal Transportation Agency, seeking information on how Waymo robotaxis contributed to massive gridlock following the July 4 Golden Gate Bridge fireworks show. More than 30 Waymo robotaxis became stuck in the Presidio parking area, some running out of charge and requiring towing.

Mahmood stated it is 'not acceptable that disruption of service, first responders and our public transit system is a side effect of autonomous vehicles' and requested city departments respond within two weeks. The inquiry follows repeated Waymo run-ins with first responders documented by TechCrunch and a July 8 NHTSA directive demanding AV companies stop interfering with emergency operations.
