The whole idea here is to get cars to ‘talk’ to each other over a wireless network. It would enable cars to share info like location, speed, direction and braking. Auto regulators say so-called vehicle-to-vehicle communication will prevent thousands of crashes each year.
Vehicle-to-vehicle communication isn’t new. It’s already being tested in the realm of autonomous driving and some automakers already offer non-V2V autonomous safety tech. Examples include blind spot detection, brake assist, and lane departure warning. What V2V does is take all of this information and transmit it to a shared network that can communicate warnings to drivers who can then make better driving decisions.
Here’s just one example. Say you’re trying to figure out whether to make a left turn across traffic lanes. A shared network could give you braking info of oncoming vehicles, so you can determine if they’re slowing down and if the turn is safe to make.
In addition to the NHTSA’s proposed rule, a similar ruling is expected by the Federal Highway Administration. It will take charge of Vehicle-to-infrastructure (V2I) communication. This involves cars communicating with their surroundings like traffic lights and stop signs.
The public comment period on the proposed V2V rule is 90 days. During this time you can send your comments to the NHTSA. A final ruling will then be made.
