They also fail to "write" human body language. Nobody else can predict what the autonomous vehicle will do.

It gets worse when a person is sitting in what appears to be the driver's seat. If the car is stopped and that person is looking toward another passenger or down at a phone, nobody will expect the vehicle to begin moving. Making eye contact with the person in that seat is meaningless, but people will infer meaning.

Great point. So much of our daily driving relies on the exchange of subtle social cues with other drivers.

that is an interesting point. cycling, I often am forced to rely on reading the driver's intentions-something I don't really want to have to do; signals obtained from person sitting in the driver seat but not operating the vehicle could be totally irrelevant to predicting the behavior of the vehicle itself (and cars are not equipped to really signal those things very well).

I have never driven a car. I walk, bike, skateboard everywhere. If there isn't a light I require human feedback before walking in front of a car. Normally I wave and they wave back. They know I am there.. I can walk.
