If you are sitting in a waymo vehicle, and somebody cuts you off - do you even notice? They don't have them round here but my idea is that the vehicle itself is doing all the work, you can just continue reading your book, chat or get on something else with little awareness of the actual journey. Does the waymo curse and shake its little fist to alert you it was cut off?

I rode with Waymo a few times and was always aware of the traffic around us. No telling if that would last once the novelty wore off.
