As both a pedestrian and a driver, I certainly have to read social cues.

If I'm walking up to a pedestrian crossing and a car is approaching, I don't just step out into the road, even though I have the right of way. I try to make eye contact with the driver to see if they recognize I'm crossing. They'll often nod or do something similar to signal that they're letting me cross.

A machine has to understand these social cues as well. It might even be helpful if the machine has a way to signal its intentions back to pedestrians.
