Waymo has enough miles that it’s ready to start quoting how many injuries it has prevented, and the number is pretty high. Its newest crash data states that it had operated a total of 271 million driverless miles through June of this year, which is 50 million more miles added in the 3 months since its end-of-March update. Over those miles, Waymo says there was an 82% reduction in crashes that caused injury, and a 95% reduction in crashes that cause “serious injury or worse” [compared to human drivers].
Waymo also says that compared to human drivers it’s reduced injury-causing crashes involving pedestrians by 93%, cyclists by 86%, and motorcyclists by 82%.
Waymo’s analysis comes from San Francisco, Los Angeles, Austin, Atlanta, and Phoenix, and its blog post includes video showing some near-misses where it says its automated system prevented an injury-causing collision.
