In fact they do need all those things. There are laws around window tinting that require some level of visibility from inside and outside the vehicle. It depends on whether it's the windshield, front windows, rear windows. At this point, Waymos are still human-drivable, and must be street-legal in every way. And it seems like all the Waymos I've met have CA plates, so they would need to adhere to the most strict regulations according to where they're registered, insured, and operated.
