Sophomore year high school physics time, back of the envelope edition:
Car mass: ~1500kg
Car velocity: lower bound, 80mph? lets call it 35 m/s
Ek = 1/2 mv^2
Wolfram Alpha cheat: .5 * 1500 kg * (35 m/s)^2 = .91 megajoules
Stopping that car with a tree dumps damn near a megajoule of energy somewhere (and that is before you consider the potential energy in the gas!). You can bet your ass a significant portion of that energy is going to be spent rapidly "disassembling" that car.
This is a more compelling argument since it presents actual substance, but it doesn't change what I was saying about the post I was replying to, nor does it change what was posted.
Congrats on your sophmore year high school physics, not real big on passive aggressiveness but I am big on logic and well-reasoned arguments. :P
