The act of a man receiving "roadhead" (oral, blowjob, bj, head, etc) from the driver of the car while sitting in the passenger side seat, while the car is in motion. This can be achieved by cruise control or telling the giver, in the drivers seat, to hit the gas or brake as the receiver steers, from the passenger side seat. Highways are the optimal.
