> Let's say you're driving through an intersection with a green light, and there's a pedestrian waiting to cross. The robot has the right of way and goes, but suddenly the pedestrian decides to cross in front of the vehicle. Even if the reaction time was 0.00 seconds it's too late to avoid a collision.

Why does a robot driver need to anticipate this? Does a human driver need to?

Er, yes? Remind me not to walk close to your car :P

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.
