A massive power outage in San Francisco over the weekend led Waymo self-driving taxis to stop working around the city.
"Significant and extensive" damage from a fire in a substation caused the Saturday afternoon outage that left more than 100,000 customers without power, utility provider PG&E said in a statement.
Videos posted to social media showed Waymo robotaxis halted in the middle of city streets and intersections with their hazard lights flashing, as traffic jams grew and drivers zigzagged around the stopped cars.
Waymo initially paused all service in the Bay Area following the outage, but has since resumed its operations, a spokesperson said in a statement.
During the outage, many traffic signals stopped working, city officials said, and Mayor Daniel Lurie deployed police officers, fire crews, and others to help with the flow of cars on the roads. Some commuter train lines and stations shut down, as well.
