The difference between old cars & new cars.
Old cars: Took less damage overall in the crash. Tended to kill and/or main the occupants.
New cars: Evaporate fairly easily during accidents, but have much higher survival rates for the occupants.
What that video shows: Kids are stupid.
Personally, I'd rather have my car looking like somebody went crazy on it with a jackhammer, and be able to walk away from the accident. As opposed to a car that only needs a panel or 2 replaced, while I look like I tried to fight it out with Mike Tyson.
