You know who I think are the biggest culprits are old ladys.
I was in Florida for spring break and we had just ate at a waffle house. We didn't have enough money to pay so I had to go to my car and dig some change out of the ashtray. While I'm lookin for quarters these 4 old ladys get into the car next to me, and the driver opens her door so hard into my car that I can hear it hit my door. Without a doubt she was responsible for one of the 4 or 5 door dents in my car, but these people were so ******* old I just let it go.
