Waymo resumes San Francisco robotaxi service after blackout chaos

Alphabet-owned Waymo has resumed its driverless ride-hail service in the San Francisco Bay Area after a temporary pause during blackouts that plagued the city beginning on Saturday afternoon.

“Yesterday’s power outage was a widespread event that caused gridlock across San Francisco, with non-functioning traffic signals and transit disruptions,” a Waymo spokesperson, Suzanne Philion, told CNBC in an e-mailed statement Sunday afternoon.

“While the failure of the utility infrastructure was significant, we are committed to ensuring our technology adjusts to traffic flow during such events,” she added.

As power outages spread yesterday, videos shared on social media appeared to show multiple Waymo vehicles stalled in traffic in different parts of the city.

San Francisco resident Matt Schoolfield said he saw at least three Waymo autonomous vehicles stopped in traffic Saturday around 9:45 p.m. local time, including one he photographed on Turk Boulevard near Parker Avenue.

“They were just stopping in the middle of the street,” Schoolfield said.

The power outages began around 1:09 p.m. Saturday and peaked roughly two hours later, affecting about 130,000 customers, according to Pacific Gas and Electric. As of Sunday morning, about 21,000 customers remained without power, mainly in the Presidio, the Richmond District, Golden Gate Park and parts of downtown San Francisco.

PG&E said the outage was caused by a fire at a substation that resulted in “significant and extensive” damage, and said it could not yet provide a precise timeline for full restoration.

San Francisco Mayor Daniel Lurie said in a 9 p.m. update on X that police officers, fire crews, parking control officers and city ambassadors were deployed across affected neighborhoods.

Waymo’s Philion also told CNBC that “While the Waymo Driver is designed to treat non-functional signals as four-way stops, the sheer scale of the outage led to instances where vehicles remained stationary longer than usual to confirm the state of the affected intersections. This contributed to traffic friction during the height of the congestion.”

Waymo “closely coordinated with San Francisco city officials,” she said, and proactively paused its service as of Saturday evening and in the first half of the day on Sunday.

“The majority of active trips were successfully completed before vehicles were safely returned to depots or pulled over,” she noted.

Amid the disruption, Tesla CEO Elon Musk posted on X: “Tesla Robotaxis were unaffected by the SF power outage.”

Unlike Waymo, Tesla does not operate a driverless robotaxi service in San Francisco.

Tesla’s local ride-hailing service uses vehicles equipped with “FSD (Supervised),” a premium driver assistance system. The service requires a human driver behind the…
