We had a dust storm pass through northern Utah today. Winds so strong several 18 wheelers were blown on their sides. The winds also kicked up so much dust that visibility went to zero in places. One of those places was I-80 west of Salt Lake City where a big rig slowed to a crawl when the visibility got bad. Unfortunately vehicles behind the truck continued at high speed (despite not being able to see ahead) and the result was a chain reaction involving 6 or so big rigs and 12 to 15 cars. One dead, 25+ injuries. Can Tesla's systems see through stuff like dust storms and slow and/or turn the car to avoid a collision?
