Waymo Cars Stalled: What Happened During the San Francisco Blackout? (2026)

San Francisco's Blackout Exposes Waymo's Vulnerability

A city-wide power outage in San Francisco has revealed a surprising weakness in Waymo's driverless taxi service. Waymo, the autonomous vehicle company, found itself in a challenging situation as its robotaxis struggled to navigate the streets during the blackout.

The blackout, caused by a fire at a power substation, left a third of San Francisco's residents in the dark. As the city's traffic signals went out, Waymo's vehicles were observed blocking intersections and causing congestion. The company was forced to suspend its service, leaving many passengers stranded.

And here's where it gets controversial: Waymo's autonomous vehicles are designed to treat non-working traffic signals as four-way stops, but the scale of the blackout led to unexpected behavior. Some cars stalled for extended periods, trying to confirm the state of intersections, while others completed their trips successfully. This raises questions about the reliability of self-driving cars in emergency situations.

Mashable reached out to Waymo for an explanation. The company's spokesperson, Suzanne Philion, attributed the issue to the widespread power outage and assured that they were working closely with city officials to resume services. However, Waymo did not disclose the extent of the impact on their fleet or why the vehicles stopped working.

But the story doesn't end there. By Sunday afternoon, power was restored, and Waymo resumed operations. The spokesperson acknowledged the challenges, stating that they are committed to adapting their technology to handle such events. But is this enough to reassure the public?

This incident is just one in a string of recent controversies for Waymo. From viral videos of driverless cars driving into traffic to reports of unauthorized passengers and software recalls, the company has faced scrutiny. And let's not forget the unfortunate incident involving a beloved neighborhood cat in San Francisco.

As Waymo works to regain trust, the public is left wondering: Are we ready to embrace a future of autonomous vehicles? And what safeguards are in place to prevent these incidents from becoming more frequent or severe? The debate continues as the technology evolves, leaving room for both excitement and caution.
