When I took a Waymo in California, it was a nearly perfect experience. The one exception was when a person in front of me stopped and tried to parallel park on the right side of the road. The Waymo wasn't giving them enough space, sort of inching forward as they attempted to back in. I felt bad - I could see as we passed that the car had stressed them out. I still think Waymos are good overall, but it kind of surprised me it didn't know how to handle this situation.
