There's no confusion here. It will be possible, but relying on it to stop traffic waves is an untenable fantasy. Even directly connected fiber optic communication has levels of unreliability that would make it untenable to drive closer than you can stop from visual sensory alone...and you want to rely on wireless communication?
At it's best, wireless communication may help traffic miles from an incident, by communicating problems (most likely with some central management system) and routing traffic around it. Visual range sensors will dominate all local interactions, just like they do with swarm coordination systems in both nature and robotics.
