When you read Google's crash reports [2], it's almost always "autonomous vehicle was rear-ended by human driver". That's happened twice at Phyllis Av. and Grant Rd. in Mountain View. It's worth a look at that location.[3] Notice the tree in the median strip on Phyllis. That's in just the right place to block Google's car-top LIDAR scanners from seeing cross traffic on Grant Rd. So the autonomous vehicle advanced at 6mph to get a better view, detected cross traffic, stopped, and was rear-ended. The same thing happened a month later, last September. The autonomous vehicle did the right thing (not seeing "hit by cross traffic" accident reports), but it wasn't what the driver behind expected.
That's what the problems look like in the later stages of development. Not reports of hitting parked cars.

Even the photos in this article are a bunch of Chevrolet dumps charging.
You're also assuming that all of the other companies wanted to sell, which isn't true.
