Yes, communicating / negotiating the decision with the other person. That's how humans do it.

Now try driving in dense NYC traffic, and you'll see humans communicating everywhere. Good luck to self driving cars in that scenario - unless humans are 100% off the roads.

Even a minority of self-driving cars will change traffic, probably for the better in the vast majority of cases. Human drivers following a self-driving car will have to adopt the self-driving car's caution, moderate acceleration, and deference to pedestrians and cyclists.

Good luck getting anywhere in Manhattan if you practice total deference to pedestrians and communicate that you do (e.g. by looking like a Google car)
