same thing I was about to say: most new cars are unibody construction, which is designed to crumple on impact, as opposed to the older style frames that would transmit the jar of the impact through the entire car..Most new vehicles are designed to save the passenger by sacrificing the car, crumpling all parts before the passenger compartment to absorb the impact. If they went old school and used steel again then they put the passengers back to more risk. I would rather trash my car in a bad accident and survive, then have insurance or warranty repair it or replace it.
the force from the crash is weakened through the front end of the car as it crushes it, so you are actually safer inside the car than you would be in an older style. This would be why most new cars are totaled when in a collision..
