Last time I was in SF I took 3 waymo rides and attempted a fourth. The attempted one was cancelled after 15 minutes of waiting for it being 2 minutes away. As best as I can tell, the waymo was stuck at an intersection where power had been lost and didn't understand it needed to treat it like a 4 way stop.
2 rides went fine though neither was particularly challenging. The third though the car decided to head down a narrow side street where a pickup in front was partially blocking the road making a dropoff. There was enough space to just squeeze by and it was clear the truck expected the car to. A few cars turned in behind the waymo, effectively trapping it in as it didn't know how to proceed. The dropoff eventually completed and it was able to pull forward
