I can tell you how do i avoid all those things.
1-Never ever ever,i park my car in a supermarket,mall or any other public parking lot,people dont consider those little digs a big deal,some of us will kill for that.
2-Never ever valet parking.
3-If you HAVE too park some were park as far as possible even if requires an extra 10 minute walk.
4-Never EVER go to a kids birthday party with your car you be sorry.
5-Dont park it on drive ways were bicycles can comute.
And the list goes on i keep my car in the garage under cover my wife and kids are not allow to be more than 4 feet close to the car
