Automobile collision/vandalism detection

I'll bet a clever electrical engineer could do this, though of course the devil is in the details.

Wire up the metal body panels of an automobile to carry a very low-voltage current. Establish a baseline. If the panel is dented or deformed, such as a fender bender or errant shopping cart, that should change the conductivity of the panel. If some kind of event is detected, some internal camera should take a set of 360 °ree; photographs every second for the next 30 seconds (or whatever) in order to catch the perpetrators.
