Front View of Group of Wrecked CarsThe Federal Department of Transportation recently revealed plans to require vehicle makers to install inter-vehicular communication devices, what the automotive trade knows as V2V technologies, that federal safety regulators say could prevent up to 80 percent of car crashes not caused by impaired drivers or mechanical failures.

The National Highway Traffic Safety Administration (NHTSA) says police reported 5.6 million crashes in 2012. About one car in seven in collision shops for crash repair cost estimates was totaled, according to insurance claims analyst. If the number of crashes shrank by 80 percent, there would be 4.5 million fewer cars for body, mechanical, and electrical parts to replace those damaged in collisions, and there would be hundreds of thousands of fewer totaled cars for processing by recyclers for scrap.

V2V technologies send ten wireless transmissions per second with car location, position, direction, and speed data to other vehicles equipped to receive them. Alerts to drivers of collision risks from slowdowns, obstructions, and curves would prevent accidents, DOT says. V2V, for instance, could help a driver decide whether it would be safe to pass on a two-lane road, make a left turn across traffic, or enter an intersection on a collision course.
