Waymo's self-driving van is headed to Death Valley

Among the challenges that come with making self-driving cars road-ready, is making sure they can withstand extreme weather. They won't be much use if they can only operate in pristine conditions. In that regard, Alphabet's self-driving outfit Waymo has been taking its cars on road trips so they can be tested in some actual weather and not just in mild Mountain View. The company tweeted a picture of one of its Chrysler Pacificas driving in some hotter temperatures as it heads down to Death Valley, where temperatures have soared as high as 134 degrees. In March, Waymo tested how its cars handle snowy conditions in South Lake Tahoe.
