21stcentury Curb feelers

I remember as a child hearing the noise when my mom would know she was close to the curb ,by the sound of the metal rods of the spring loades curb feelers. This device had prevented many a family argument over the loss of exterior wall of a tire caused by contact with the curb and tire and the untrained or incompetant family driver. With the use of simple acustic measuring devise set to set an alrm at a preset distance (similur to the ones used to measure inside walls) mounted on the fender well of your car and wired to an audible screech. You could revise the invention of days past. This would also work for running over bicycles,dogs, or any other unfortunate item in the pathway of the unknowing speedster.
