Ultrasound Horn

Although most of the time that a driver honks his horn, he desires that the sound be heard in all directions, there are occasions when he really only wants the driver of the car in front of him to hear the horn.

I propose to have, in addition to the regular car horn, a sound from ultrasound device which projects a car-horn-type-sound directly forward.
