Plus there's no crumple zone back there...it's not meant to deform much in an accident. That's some serious sheet metal back there-a pickup truck backed into my wife recently, striking the right rear quarter panel quite hard. My wife was completely surprised at how little damage was done to the sheet metal. Pretty thick sheet it would seem.
