People seem to think that carbon fiber is really strong and for some reason, they like to stand or sit on cf hoods to show off and say they "look, they don't dent" I have seen a few cf hoods that can withstand this abuse(really expensive top-end hoods, $1000 and up) but the ones that can't, look like that. Either he stood or sat on it, or he used your car to get lucky with a lady friend... right on your hood
