bk, I did it once. In the parking lot of a bookstore in Athens, GA. Pulling into a regular old parking space, normal thing, the front of my car hits the side of another car. There was disbelief, because it was something I'd never had trouble with, and then suddenly, I've damaged someone's car. I'll never forget the girl, blonde, sorority gal, getting out of her car, taking a look, and saying, "That's okay. My dad was going to buy me a new car next month anyway." The relief!
