As far as the door dings go, Imagine walking into your local PD with a dash video of a guy/gal walking away from your car, and explaining to them that your camera turns on when your car is bumped so it must be the guy that dinged your car. Even IF you get the lic. plate as he/she drives off. Good luck proving it without footage of the door meeting your car.
My $.02 and that may be all its worth, but it is Mine. I'll put that coin in my gas tank and have some fun instead.
