V2V communication is a viable way to mitigate accidents amongst autonomous vehicles.
Engineers have known for some time that if cars could only “talk” to each other, they could avoid a lot of accidents.
Vehicles could be driven more safely with information about another car, obstacle or pedestrian around a blind curve, for example.
But the hurdles to implementing these systems are numerous: they require a legal framework and the allocation of wireless spectrum to enable vehicle-to-vehicle (V2V) communications.
