While the robot can't see round blind corners in the manner a person could, visually processing it, we could require aircraft style transponders on all road vehicles, which would then allow your robotic car approaching a blind corner to know of there's anyone on the other side. It would also allow unambiguous communication as to how fast each vehicle is travelling, and their intentions - think in terms of the brake and indicator lights also being part of the transponder signal.
