Because how the car crumples is pretty much irellevant.Boogahz wrote:You would have to test every car against every other car made then. How do you know that Car A will crumple in the same place as Car H in an impact with Car B? Heck, what about Car K, where will it crumple, and where will it resist doing so when it impacts your car?
They test passenger compartment integrity.
They test for intrusion into the passenger compartment.
They perform what are essentially a worst case scenario crash tests.
If they were to perform crash tests that mirrior reality, they would be testing minor fender benders for months.
A head on crash @ 40-50 miles per hour is the worst case scenario in terms of the amount of energy an automobile will have to absorb.
You should take some time and read up on the practices and standards used in crash tests.
It's really quite interesting.
Name another type of accident (aside form head on and t-bone) that will cause more potential damage to a car and it's occupants.Sure, if you decide to run head first into a brick wall then the tests are pretty conclusive, but that's rarely the case.
Do you think that they crash a single car?Crash tests rarely (because it would be way to costly) take into consideration, angles of impact, varying speeds of not only the tested car, but the object it's hitting, using car vs car instead of a wall or whatever they use, the sizes of cars that could hit the car, etc. that happen in almost every real life crash.
They actually test at different speeds and angles.
But as for crashing a vehicle into another vehicle...
Do you understand the concept of worst case scenarios?
Why would they crash a car into another car when they can simulate a more severe impact by crashing it into a solid block of concrete? A car hitting a solid, unyielding object will be required to absorb the full force of the impact. With a car hitting another car, the impact of the crash is distributed between the two vehicles. The results would be about as accurate as crashing a car into a block of jello.
