From my perspective, as a relatively early adopter of Waymo (60+ rides). I have zero gripes with the driving itself. In fact I've seen Waymos do things that no human would be able to do*. Drop-offs and pickups I'd like to see improvements made like getting a bit closer to the curb. Occasionally the route selections make no sense at all.
* Waymo made a right turn up a steep hill. Two lanes each way. It then pulled a bit into the left lane abruptly and I didn't get why until a split second later a skateboarder was crouched down and went by on my right against traffic. There was zero chance a human would pull that off. Not enough time for a head check or mirror check. There wouldn't have been an accident but the Waymo clearly has insane reaction time and vision advantages - and uses them.
