Waymo autonomous vehicles (AVs) stopped and blocked traffic in San Francisco on Dec. 20 after traffic lights stopped working due to an electrical power outage caused by a substation fire, forcing the company to temporarily suspend services.
The robotaxi company said its vehicles are designed to treat nonfunctioning traffic lights as four-way stops, but that the scale of Saturday’s outage had created unusual conditions. Therefore, the company paused services, resuming on the afternoon of Dec. 21.
