Talking Cars Coming Down the Pike

The U.S. Department of Transportation on Monday announced it would move forward with a plan that would make car-to-car communication mandatory among light vehicles, a measure that could lead to safer roads. Vehicle-to-vehicle, or V2V, communication allows cars to share data including speeds and brake applications with nearby cars. That data can then help warn drivers about possible collisions. For instance, a car that unexpectedly slams on the brakes could communicate the action to nearby vehicles, which then could warn their drivers.
