Waymo's Driverless Cars 'Froze' Across San Francisco During City-Wide Blackout
A major power outage in San Francisco on Saturday caused Waymo's driverless cars to stall at intersections with dead traffic lights, leading to significant traffic jams and raising questions about AV reliability.
Robotaxis Stall at Dead Intersections, Causing Gridlock
When a power outage knocked out electricity to a third of San Francisco on Saturday, Waymo's fleet of autonomous vehicles seemingly didn't know how to cope. According to videos posted across social media, the driverless cars came to a halt at intersections where traffic lights had gone dark, causing long lines of frustrated human drivers to get stuck behind them.
The incident highlights a critical vulnerability for even the most advanced autonomous systems: their dependence on stable, functioning city infrastructure. While a human driver can navigate a powerless four-way stop through gestures and social cues, Waymo's AI appeared unable to handle the chaotic, unscripted scenario. The vehicles, unable to proceed, effectively became high-tech roadblocks.
The tech blog Boing Boing, which first reported on the social media posts, pointed to the widespread confusion caused by the stalled vehicles. The blackout didn't just turn off the lights; it stress-tested the city's robotic vehicle fleet in a real-world failure scenario, revealing a significant hurdle on the road to fully autonomous smart cities.
