Waymo is using its self-driving taxis to create real-time weather maps

Self-driving cars frequently have trouble with poor weather, but Waymo thinks it can overcome these limitations by using its autonomous taxis as weather gauges. The company has revealed that its latest car sensor arrays are creating real-time weather maps to improve ride hailing services in Phoenix and San Francisco. The vehicles measure the raindrops on windows to detect the intensity of conditions like fog or rain.
