The U.S. Department of Transportation and the University of Michigan are testing out technology that allows cars to "talk" to each other. The idea is that these safety devices would allow drivers to be aware of the presence and intention of vehicles around them.
When the technology will make its way into cars and trucks everywhere is unclear. The National Highway Traffic Safety Administration has the authority to order the devices placed in all new cars, but LaHood said they'll have to study the data before making any decision. The data will be available in about a year.
In a demonstration at the Transportation Research Institute, a Volkswagen GTI equipped with a device got a signal that a car up ahead of it had braked. The warning allowed the GTI driver to slow down before seeing the brake lights on the car in front of him. The device also warned the GTI driver at a stop sign that another car was about to speed through the intersection.
