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.
