cars today were made to crumple bcoz, back in the 30s-50s, cars were rigid structures. that fact alone caused more deaths then airplane crashes in the 50s.
when a car body withstands impact and keep its form, the energy and momentum of the crash has nowhere to escape and is not absorbed by the car. thus, the passenger is their own cushion, airbag AND crumple zone. u know what happens when a person gets crumpled. they die.
the reason engine compartments and front/rear chassis crumple to nothing is to dissipate/distribute/disperse the large amount of energy created during a sudden impact. energy cannot be cancelled out, it has to be converted to another form. the engine, front chassis and such are destroyed bcoz they absorb and disperce most of the energy so that the passengers arent subject to excessive forces.
the only important thing in a modern day car accident is that the passenger cabin stays relatively intact (i.e. not crush a person). the frontal or rear end ruin is the cushion that saves our sorry lives. if cars were still made for "i still love this car, and it's looks are more important than my life" mindset, u'd be lucky to be still alive or born at all.
on a human side note, we malaysians easily get obsessed with ruined belongings (in this case cars) bcoz its so expensive. its not really our fault for feeling fucked when our cars crash bcoz circumstances in our beloved land dictates that its hard to ACQUIRE replacements. we should be more careful and in that, nobody else is to blame but ourselves. other than that. its not our fault car prices have overtaken the price of our lives. we worry more about the car's condition than our safety most of the time. of course, some are ignorant about the purpose and technology of car passenger protection in an accident.
dont believe me? watch Discovery Channel more and u might learn something before u embarrass urself in a car related forum. now u know.
