Some kind of vehicle-to-vehicle standard should be made. I don't think the first application will be intersections; that's really more suited for 'manual exclusion' zones, which are a ways off. But one really interesting application would be road-trains for freeways. You'd cut down on drag significantly, and could probably make it work on manual-driving roads with object/hazard communication and real-time agreement on emergency maneuvers (e.g. every other vehicle swings out to the breakdown lane, simultaneous braking, etc.). Drag is ~2/3^rds of the energy loss of a big-rig on the highway, so imagine the kind of range a battery electric truck could get in 'road train' mode.
