The U.S. DOT has taken a major step toward requiring that all vehicles be equipped with V2V technology. The new rule will call for standard V2V technology to be phased in over several years, and the technology will have to clear administrative obstacles and a comment period.
Transportation Secretary Anthony Foxx says the goal is to see this technology put in place as soon as possible.
V2V communication uses technology similar to WiFi allowing cars in close proximity to share information, like speed and direction, several times a second.
This allows the car to warn a driver before changing lanes or about a hazard ahead.
V2V enabled vehicles may also be able to communicate with infrastructure and the environment around it.
Early cost estimates V2V technology will be available for about $100 per vehicle but that price is expected to drop as time goes on and use of the technology becomes more widespread.
