SAN FRANCISCO (KRON) -- A San Francisco supervisor is calling for a hearing to look into Waymo's emergency operations after the autonomous robotaxis caused traffic chaos during a blackout over the weekend. The days-long power outage began Saturday and as of Monday, is still ongoing. At its height, the blackout left some 130,000 customers without power across San Francisco. During the outage, there were numerous reports of halted driverless Waymos idling at intersections with darkened traffic lights. Waymo temporarily paused its service in the city on Saturday. On Monday, SF Supervisor Bilal Mahmood said San Francisco residents deserved answers from company. Missing swimmer reported in Monterey County beach, possible shark attack: officials "This weekend has been a disaster for thousands of residents across San Francisco who were left without power during the holiday season," Mahmood said. "Making matters worse, we saw stalled autonomous vehicles creating massive traffic disruptions for residents, and severely impacting the Fire Department's ability to respond to the fires as quickly as possible." In addition to Waymos disrupting traffic, there were additional reports of the halted driverless taxis hampering San Francisco Fire Department vehicles. "San Franciscans deserve answers into why Waymo was unable to handle such a large-scale infrastructure failure, and what they plan to do about it in the future to mitigate these types of impacts," Mahmood said. "I believe autonomous vehicles can play a role in the future of transportation to reach our Vision Zero goals, but only when these companies operate responsibly, especially in light of disruption to city operations during an emergency." Vision Zero is a city initiative to end traffic deaths on city streets. Mahmood also announced he would be cosponsoring Supervisor Alan Wong's call for a hearing into PGE to demand answers on how an electrical fire led over 130,000 without power. "The magnitude of the outage this weekend is unheard of in recent San Francisco memory, and the impact on our most vulnerable neighborhoods from Tenderloin to Civic Center to Western Addition and Haight Ashbury deserve a voice," Mahmood said. "In collaboration with Supervisor Wong, I look forward to holding PGE accountable for what went wrong, what measures can be taken in place, and start a conversation on how San Francisco can chart its own destiny with public power." Both hearings are set to be introduced when the SF Board of Supervisors resumes sessions on Jan. 6, 2026. As of Monday morning, several thousand customers in San Francisco remained without power, according to the PGE outage map. ...read more read less
