An anonymous reader quotes Engadget:
A University of Michigan public-private partnership called Mcity is testing V2V, or vehicle to vehicle communication, and has found that it makes their autonomous prototypes even safer. V2V works by wirelessly sharing data such as location, speed and direction. Using DSRC, or Dedicated Short Range Communication, V2V can send up to 10 messages per second. This communication allows cars to see beyond what is immediately in front of them — sensing a red light around a blind curve, or automatically braking for a car that runs a stop sign… The catch of V2V? It has to be installed in the majority of cars and infrastructure (such as traffic lights) to function adequately.
