> There was a collision on Geary Boulevard where a Waymo vehicle detected a speeding car during a left turn and stopped, rather than accelerating to escape. That's their worse accident so far, and the other driver was at fault.
You're thinking of Cruise.
The most common single problem with serious autonomous vehicles right now is being rear-ended by human vehicles while cautiously entering intersections. The usual sequence of events is, autonomous vehicle approaches intersection where the view of the cross street is obstructed, autonomous vehicle starts to enter intersection, detects cross traffic, stops, and is rear-ended. There are dozens of those in the California DMV reports.
This will probably get better as more vehicles get automatic radar-controlled braking, which is good at preventing low-speed rear-ending.
