Power Outage Strands Waymo's Autonomous Vehicles in San Francisco

Published on January 06, 2026 | Translated from Spanish
Several Waymo autonomous vehicles, with their distinctive design, stopped on the shoulder of a San Francisco street, with the city in the background, illustrating the service disruption due to a power outage.

Power Outage Strands Waymo's Autonomous Vehicles in San Francisco

A power outage in a sector of San Francisco disrupted the normal operation of several autonomous vehicles operated by Waymo, Alphabet's company. This event demonstrated how failures in basic infrastructure can directly affect advanced transportation technologies. 🚗⚡

Robot Cars Execute Their Safety Protocol

Upon losing connection with Waymo's data centers, the driverless cars immediately activated their contingency protocol. This system, which relies on sensors and software that require constant power, ordered the vehicles to stop in a controlled manner in the safest available location, usually at the edge of the roadway.

Immediate Consequences of the Failure:
  • The vehicles stopped in traffic lanes and shoulders, causing obstructions.
  • Waymo's assistance teams had to manually recover the units.
  • Traffic jams and some confusion were created in the streets affected by the outage.
A technology designed to avoid human errors is at the mercy of something as mundane as a blown fuse or a damaged cable.

The Debate on Infrastructure Needed for the Autonomous Future

This incident reignites the conversation about what cities need to integrate autonomous mobility on a large scale. Experts point out that perfecting algorithms is not enough; it is vital to ensure that power and data networks are robust.

Key Factors Exposed by the Outage:
  • Connection Dependency: Autonomous vehicles require a stable and continuous data link to operate.
  • Power Supply Reliability: A localized outage can paralyze not only traffic lights, but entire transportation fleets.
  • Urban Resilience: Traditional infrastructure must evolve to support technologies that promise to transform how we move.

An Autonomous Future Still Plugged into the Old Grid

The irony of the event is palpable. Cars capable of navigating complex intersections are forced to stop due to the absence of a network signal, evidencing that the future of autonomous driving still depends on the old electrical grid. This event serves as a practical reminder that developing cutting-edge technology also involves strengthening the basic systems on which it operates. 🔌🤖
