Waymo’s robotaxis are basically mobile weather stations now

Autonomous vehicles have difficulty navigating bad weather. Heavy rain, snow, and fog can do a lot to scramble an AV’s perception systems, which largely rely on cameras, radar, and lidar to “see” the world around it. Wet roads can create reflections that confuse cameras. Fog can screw up sensor data. And ice can form on the lidar, inhibiting the sensor’s ability to send out laser points to gauge distance from other objects on the road.
