The extensive power outage in San Francisco led to traffic turmoil as Waymo’s autonomous taxis found themselves immobilized on the city’s streets.

On Saturday night, the Bay Area plunged into darkness, affecting 130,000 PG&E customers, which is roughly 30 percent of San Francisco’s population.

Although electricity was eventually restored for 95,000 of those affected later that evening, many residents were forced to dine by candlelight or conserve their device batteries to navigate the night.

The blackout also caused major disruptions to public transportation, with BART stations experiencing considerable delays citywide.

By Sunday morning, around 35,000 residents remained without power.

Adding to the chaos, the futuristic driverless taxis from Waymo, which made their debut in the city last year, stalled in the middle of the streets, contributing to the mayhem.

The cars appeared to be frazzled by traffic lights malfunctioning amid the blackout, so a lot of the vehicles came to a complete stop, leaving those driving other cars to be hit with mayhem. 

At least one person was reportedly left stranded inside a Waymo car during the outage, SF Gate reported.

Residents posted images to social media showing how they had to adjust to the darkness as they went about their night

Waymo suspended service at 8pm Saturday after getting reports that the driverless cars were causing dangerous traffic jams. 

‘We have temporarily suspended our ride-hailing services given the broad power outage in San Francisco,’ Waymo spokesperson Suzanne Philion told the outlet. 

‘We are focused on keeping our riders safe and ensuring emergency personnel have the clear access they need to do their work.’ 

Meanwhile, pedestrians took to social media to show the disorder in the Bay Area. 

Several Waymo cars were seen stopped at traffic lights, while others were parked in the middle of busy intersections.

‘In case anyone was wondering how the Waymos would respond in the event of a power outage, the answer is “not well”,’ a user posted to X alongside a video of halted Waymo vehicles while other cars maneuvered around them as best as they could. 

‘Human drivers handled it like a 4 way stop. Waymo rolled over and played dead,’ another said. 

While people out on the street struggled to go about their lives, others at home were faced with challenges of their own. 

As of Sunday morning, 35,000 San Franciscans are still without electricity

One couple posted a picture to Facebook showing them having dinner with multiple candles illuminating the room. 

‘Dinner by candlelight (due to a massive power outage in SF!),’ the man wrote. 

Another person set their open MacBook laptop on top of their toilet so they could have a little light while they took a shower. 

‘Desperate time (taking a shower during sf blackout) call for desperate measures (burning my laptop’s battery for illumination),’ the X user wrote. 

The height of the blackout impacted several neighborhoods across the Bay Area, including Richmond, Hayes Valley, Sunset, Haight Ashbury, Forest Hill, all of Golden Gate Park, parts of downtown, South of Market, and Presidio. 

Power outages were reported by residents as early as 9.40am local time in some parts of San Francisco. 

The issue is believed to have originated from a PG&E substation at 8th and Mission Streets, Supervisor Matt Dorsey said on social media. 

A local shared a picture of a room in their home being lit up by several candlesticks and a lantern during the peak of the outage

Then, around 3.15pm, the San Francisco Fire Department responded to a fire at the location. 

Dorsey said the exact same substation, or electrical grid control center, was responsible for a blackout on December 21, 2003. 

That emergency affected around 120,000 customers. 

The company does not know for sure what caused the blackout, and continues to investigate, according to PG&E spokesperson Edgar Hoida.
