Discreet S.O.S. Buttons

This idea is intended to prevent you from being kidnapped in your own vehicle. Basically, there are buttons placed discreetly throughout the vehicle, buttons which are not visible unless you (the owner) know where to look, because you chose the locations. Suggested locations are in the trunk, on the back of the steering wheel, recessed into the steering wheel and flush with the surrounding material (not visible from any seat, and you can't feel it unless you have very sensitive fingers), in the back seat between the seat cushions, etc. The buttons, when pressed in a password sequence that you set (to prevent them from being accidentally pressed) send a distress signal to the police via OnStar, which they use to track your vehicle with the OnStar GPS feature. These buttons allow you to signal the police discreetly, without letting your kidnappers know you're doing it. This way, when the police pull them over, they're taken completely by surprise.
