Waymo cars refuse to drive in unsafe conditions

Heavy rain and blizzards aren't the only forms of severe weather Waymo's self-driving vehicles encounter on the regular. In a blog post published this morning, the Alphabet subsidiary laid out the ways its cars in over 25 cities tackle fog, dust, smoke, and other dangerous conditions that trip up even human drivers. "Challenging [environmental] conditions, which affect human driver and vehicle performance, are one of the leading contributors to crashes on our roads … Poor perception creates significant risk for other road users including pedestrians, cyclists, and other vehicle occupants," wrote Waymo chief safety officer Debbie Hersman. "Waymo is working hard to master a variety of weather scenarios as part of our mission to improve road safety." To this end, Waymo says its autonomous vehicles are designed to detect sudden extreme weather changes, such as a snowstorm, that could impact their ability to drive safely.
