My son used to work at a local car dealer as a lot attendant. He did horrible things to other people's cars, including teaching himself how to drive a manual transmission. He tore the mirror off an Armada, scraped up the side of a "Z" by going through a curve in the road "a little hot" during a refueling run. He also learned how to improve his gas mileage by drafting semi's on the highway when he did dealer trades. He claims to have been one of the more "tame" drivers. Based on his stories, he was probably right.

(and, YES, I did tell him he was an a$$-hole!)
