As Consumer Reports has been following the progress of NHTSA’s consideration of vehicle-to-vehicle communications (V2V) technology with great interest.  This technology has potential to significantly improve traffic safety by giving drivers an early warning of yet-unseen crash hazards posed by other vehicles.  More broadly, vehicle-to-infrastructure (V2I) and vehicle-to-pedestrian (V2P) technology – collectively, V2X – could enable drivers to obtain advance warning of other potential road hazards, and could improve pedestrian and cyclist safety as well.
