How about making eye contact? When I'm driving, eye contact & facial analysis ("did that person see me?") is significant in my risk assessment of other vehicles. That is, if I know that the other driver knows, then I don't have to worry as much. I will still be careful, but I don't have to be quite as wary. It sounds like the equivalent of eye contact for automated traffic is the "full network of communicating cars", but there must be a middle ground with mixed traffic, where automated cars are extra-careful about manual vehicles. Will that be annoying or reassuring to other drivers?
