Last Thursday. I called support after 10 minutes to cancel the ride but the car started moving while I was on the call.

That particular one was a traffic light green light with a "do not queue over intersection" area specifically designed to allow cars in my lane to turn onto the main road. The Waymo can't see that there's a gap in the lane it wanted to turn into, and was too conservative about queuing over the intersection at an angle when the light was green like any human would do.
