I was at the Phoenix a few months ago And one of the passengers didn’t close the back hatch all the way in the Waymo just sat there with blinking lights until Waymo sent out a tech to reboot it. Not very solid yet.
I saw a video of a Waymo in Phoenix where the car just kept driving in circles of a hotel parking lot. The passenger videoed himself calling tech support. They couldn’t even shut the car off or reboot it remotely.
