To add another car-damage-related fear, how about grocery carts? Or rather, the idiots who slam them into people's cars, or leave them in a position to be slammed into or roll into a car. Yesterday I went to the grocery store and started to pull into a spot ... well, there was a cart in it, very close to the next car over ... if I hadn't been paying as close attention, I would have knicked the cart and sent it slamming into the poor car next to me. What really ticked me off further is that there was a grocery cart port TWO SPOTS DOWN! How is anyone THAT lazy? (FWIW, I parked elsewhere then went back and got the cart for the sake of the guy whose car it was ready to strike). Several times I've come out of various grocery stores and found a cart with its nose up against my door or bumper. Not that they do major damage, but the little blue/red/whatever scuff marks add up. I guess that's more of a pet peeve than a fear ... but ...
