The rules could take effect in just a couple years and would add as much as $350 to a vehicle's price.

The United States Department of Transportation believes that vehicle-to-vehicle (V2V) communication would make driving significantly safer, including preventing around 1,000 deaths a year. The agency is proposing a mandate that would bring a standardized version of the tech to every new vehicle sold in the country.

As the name implies, V2V communication lets vehicles exchange information with each other. Under the DOT’s proposed standard vehicles would send and receive this data to traffic up to 984 feet (300 meters) away, even those not visible to a driver. Each vehicle does not have a specific I.D, and the transmissions don’t include any personal info, which should reduce privacy concerns. The system would then act as an extra backup to existing safety devices. For example, your car’s adaptive cruise control would know about stopped traffic ahead and could react sooner to the situation.

V2V communication also has the potential of making autonomous vehicles even better. They already have a bounty of sensors, but V2V can sense traffic that’s even farther away. By combining the two, there’s more data that software can use for making decisions about controlling the vehicle.

NHTSA estimates the V2V equipment and infrastructure would add $341-$350 to a vehicle’s cost in 2020 and would fall to $209-$235 by 2058. The agency’s calculations indicate the tech would save $54.7 to $74.0 billion after fleet-wide adoption because of the improved safety.

The DOT is now opening up the proposal for public comment for 90 days. Once implemented automakers would need to put the tech on half of their new vehicles within two years, according to Automotive News. The mandate would extend to a company’s entire lineup in four years.

The government is also looking at standardizing Vehicle-to-Infrastructure (V2I) communications. This is similar technology that allows exchanging information with things like traffic lights, stop signs, and even work zones. Audi is already experimenting with a similar system by telling drivers how long until a traffic light changes.
