If you’ve bought a new car lately, you know there’s an incredible amount of tech going on that has nothing to do with driving. My new car has weather radar maps, sports scores, movie times, and even Open Table available on the touchscreen. But a proposed rule from NHTSA (National Highway Transportation Safety Administration) would have every car be able to talk to every other one.
Under the proposed rule, would mandate vehicle-to-vehicle (V2V) communication technology on all new light-duty vehicles. NHTSA says that would help enable a multitude of new crash-avoidance applications that, once fully deployed, could prevent hundreds of thousands of crashes every year by helping vehicles “talk” to each other.
“We are carrying the ball as far as we can to realize the potential of transportation technology to save lives… This long promised V2V rule is the next step in that progression. Once deployed, V2V will provide 360-degree situational awareness on the road and will help us enhance vehicle safety.” – U.S. Transportation Secretary Anthony Foxx
The proposed rule announced December 13, 2016 would require automakers to include V2V technologies in all new light-duty vehicles. The rule proposes requiring V2V devices to “speak the same language” through standardized messaging developed with industry.
NHTSA says it would help with safety, mobility, and the environment
“Advanced vehicle technologies may well prove to be the silver bullet in saving lives on our roadways. V2V and automated vehicle technologies each hold great potential to make our roads safer, and when combined, their potential is untold.” – NHTSA Administrator Mark Rosekind
And that’s just the first step. NHTSA also hopes to get other things to talk to cars, such as traffic lights, stop signs and work zones.
NHTSA estimates that safety applications enabled by V2V and V2I could eliminate or mitigate the severity of up to 80 percent of non-impaired crashes, including crashes at intersections or while changing lanes.

MORE FROM NHTSA:
V2V devices would use the dedicated short range communications (DSRC) to transmit data, such as location, direction and speed, to nearby vehicles. That data would be updated and broadcast up to 10 times per second to nearby vehicles, and using that information, V2V-equipped vehicles can identify risks and provide warnings to drivers to avoid imminent crashes. Vehicles that contain automated driving functions—such as automatic emergency braking and adaptive cruise control—could also benefit from the use of V2V data to better avoid or reduce the consequences of crashes.
V2V communications can provide the vehicle and driver with enhanced abilities to address additional crash situations, including those, for example, in which a driver needs to decide if it is safe to pass on a two-lane road (potential head-on collision), make a left turn across the path of oncoming traffic, or determine if a vehicle approaching an intersection appears to be on a collision course. In those situations, V2V communications can detect developing threat situations hundreds of yards away, and often in situations in which the driver and on-board sensors alone cannot detect the threat.
