Waymo says that some of its driverless robotaxis lose power while stuck in heavy traffic during San Francisco’s July 4 holiday events and need to be towed. Multiple outlets report that several vehicles become stranded on city streets as traffic congestion builds around Fourth of July celebrations. NBC News and Yahoo News describe the company’s account that batteries die while the cars are caught in gridlock, leaving vehicles unable to continue. Business Insider likewise reports that Waymo attributes the disruptions to the volume of traffic on the holiday. The Next Web adds that the stalling contributes to broader traffic problems during the holiday, and it reports an incident involving a vehicle that drives over a lit firework and catches fire. Across the reports, the common theme is that the affected robotaxis are unable to move due to battery depletion during extended delays, prompting towing and raising questions about how the vehicles handle prolonged stop-and-go conditions during major local events.
