Waymo’s winter plan: robotaxis with snow tires, sensor wipers and the right to stop

A robotaxi that refuses to drive is not a failure, Waymo argues, if the roads are bad enough. The company has laid out how it will handle snow, ice and heavy rain this winter, and pausing rides is an explicit part of the plan.

The admission is the interesting bit. Waymo says that when forecast or live conditions go beyond what its safety framework has validated, it will cut its service area or stop rides entirely, sometimes for hours and possibly for days. Riders may also see service paused while their own street looks fine, because a storm can hit one side of a city and miss the other.

To judge that patchwork, every car doubles as a mobile weather station, sharing road and traction data across the fleet, and the company also listens to local officials about gritting and closures. The sixth-generation Waymo Driver combines cameras, radar and lidar, with built-in heaters and tiny wipers to keep the sensors clear, so one system can cover for another when a whiteout blinds the cameras. The car also measures grip at each wheel and adjusts steering, braking and acceleration as it changes, while cars in the winter fleet get snow tires.

Testing so far spans tens of thousands of real miles in Upstate New York, Michigan’s Upper Peninsula and the Sierra Nevada, plus simulated black ice and whiteouts. This season Waymo adds closed-course work and heavy snowfall data collection in Alaska, using its new Ojai vehicle.

Being upfront about pauses is the honest approach, and it will matter more as the service reaches snowier cities such as Denver. The company says riders should check the Waymo app and its service updates page before counting on a ride in a storm.
