An excessively risky sexual maneuver performed between a man and women or, alternatively, a man and man whilst operating a motor vehicle. In a role reversal of the classic 'road head' the vehicles operator 'ducks' into the passengers lap to perform felatio whilst the passenger 'covers' (ie; takes control of the steering mechanism) until climax and/or satisfaction has been reached.
