Connected vehicle technology enables cars, trucks, buses, and other vehicles to "talk" to each other with in–vehicle or aftermarket devices that continuously share important safety and mobility information. Fully automated, autonomous, or "self–driving" vehicles are defined by the U.S. DOT's National Highway Traffic Safety Administration (NHTSA) as "those in which operation of the vehicle occurs without direct driver input to control the steering, acceleration, and braking and are designed so that the driver is not expected to constantly monitor the roadway while operating in self–driving mode."
