The U.S. National Highway Traffic Safety Administration (NHTSA) has issued a report titled “Vehicle-to-Vehicle [V2V] Communications: Readiness of V2V Technology for Application” and seeks comments on its preliminary research as to the technology’s costs and benefits, and “additional information, data, and analysis that will aid the agency in developing an effective proposal to require new light vehicles to be V2V-capable.” NHTSA believes that this technology could prevent some 592,000 crashes and save 1,083 lives annually at an approximate cost of $341 to $350 per vehicle in 2020. Comments are requested by October 20, 2014.

NHTSA suggests that V2V capability will not develop without regulation, “because there would not be any immediate safety benefits for consumers who are early adopters of V2V. V2V begins to provide safety benefits only if a significant number of vehicles in the fleet are equipped with it and if there is a means to ensure secure and reliable communication between vehicles.” Among the questions NHTSA would like commenters to address are how its legal authority would apply to various V2V system technologies, whether it should include technical standards in its V2V rule to ensure compatibility, whether these systems should last the life of the vehicle, if requiring V2V on new vehicles will spur the development and application of retrofits for vehicles already on the road, and how to secure privacy interests and prevent cyber-attacks. The report also addresses legal liability issues that are similarly open for comment. See Federal Register, August 20, 2014.
