Waymo’s driverless robotaxis failed spectacularly during San Francisco’s power outage, grinding to a halt in traffic and exposing the dangerous fantasy that unproven autonomous vehicles can replace human judgment in critical situations.
Story Highlights
- Waymo robotaxis stalled in San Francisco streets during power outage, creating traffic chaos
- 130,000 customers lost power after substation fire, revealing autonomous vehicle vulnerabilities
- Tesla’s human-supervised service remained operational while fully driverless Waymo failed
- MIT expert warns cities aren’t ready for mass deployment of autonomous vehicles
Autonomous Vehicle Technology Fails During Crisis
Waymo’s fully autonomous robotaxis demonstrated their fundamental weakness during San Francisco’s massive power outage on December 20, 2025. Multiple vehicles stopped dead in traffic as the city’s electrical infrastructure collapsed, with resident Matt Schoolfield witnessing at least three Waymo cars “just stopping in the middle of the street” between 6 p.m. and 9:45 p.m. The failures occurred despite Waymo’s claims that their vehicles treat non-functional traffic signals as four-way stops, proving the technology cannot handle real-world emergencies.
Bad look for Waymo. Lots of reports out of SF where the power outage caused its robotaxis to stop in traffic, causing jams.
On the other side, the Tesla robotaxi fleet (& personal FSD users) continued the service without hiccups.
