Dings. I've obsessed about this to the point of referring to the crime as "hit and run". I park so far away from the front door of stores that even my kids dog me about it. I just got my car painted 2 weeks ago, and now I'm afraid to even drive it.
Ok, then I think, F this, Im going to fight back.

I spent a lot of years in car stereo, doing a lot of alarms and figuring out unique ways of securing a car. It hits me while Im watching COPS or some show like that where the cops' car is filming a traffic stop-turned murder. WE CAN DO THAT TOO!!!!
Its called the DentCam. Its triggered from a proximity sensor(motion sensor) and films about 30 seconds through a panoramic camera mounted in the rear of the cars' headliner. The idea is that you will hopefully get film of someone dinging your car, then pulling off and you hopefully get a tag#. Then pop the VHS tape out of your trunk and send a copy to the offender after you run their tag at DMV with a bill for estimated charges.
I hope no one steals my idea, I am wiring the prototype now. I'll be sure to give all you guys discounts when I develop the product. My wife thinks Im nuts, obviously, she doesnt read these boards. I bet sher wants one after I finish it.
