There are Waymos that drive through my workplace all night long. Like literally every 10 minutes. They cause problems all the time, as we have semi tractor-trailers trying to dock, and they'll block their movement and then just sit there waiting. They started putting up cones so they wouldn't pull through but now all the legitimate traffic has to get out and move them around every time they want to come through.
One time I blocked 3 of them in for several hours by trapping them by putting more cones behind them, such that there was no exit. That was fun.
