The metal may not last long under current, but it doesn't have to. The other popular one is to wire voltage to the door knob and the welcome mat, grow ops often do this to the door of the house with straight 120V AC.
If you want to know who's messing with your rides, use a strong enough DC current and they'll be stuck there (literally) waiting for you to turn it off.
