They do follow hand signals from police. There are many videos documenting the behaviour. Here is one from waymo: https://waymo.com/blog/2024/03/scaling-waymo-one-safely-acro...

Look for the embed next to the text saying “The Waymo Driver recently interpreting a police officer’s hand signals in a Los Angeles intersection.”

Or here is a video observing the behaviour in the wild: https://youtu.be/3Qk_QhG5whw?si=GCBBNJqB22GRvxk1

Do you want confirmation about something more specific?
