San Francisco — Waymo resumed robotaxi service on Sunday after temporarily suspending operations Saturday when a fire at a PG&E substation cut power to roughly 130,000 customers, causing traffic lights to fail and multiple Waymo vehicles to stop at intersections, blocking streets and prompting the company to pause service. Social media videos showed cars halted in intersections with hazard lights blinking; Waymo said most trips in progress ended normally and that vehicles treat non-functioning traffic lights as stop signs. The company said it will integrate lessons from the event and pursue software updates. Based on 6 articles reviewed and supporting research.
