45 mph is 45 mphWhat really are the odds of a crash going down like they test anyways? A perfect 30% or whatever offset at 40 or 45mph. In the real world that represents a pretty small number of accidents.
Secondly, ive always heard (maybe its not true, but lets assume it is) that a vehicle on vehicle collision at 45mph would be roughly equal to the force of a single vehicle hitting a solid object at 90mph.
So what do they use? 45mph right? Thats equal (roughly) to a vehicle on vehicle crash at 22.5mph. Thats ridiculious. Run them into that barrier at 90 to really simulate a 45mph head on.
Plus....usually after a collision the vehicle goes flying and hits god knows what else, once the crumple zones are destroyed and the airbags blown theres not much left to protect you when you go into a building, tree, or whatever else. Atleast with a real chassis (IE, frame) its going to hang on till the bitter end.
In the real world size matters.
Two cars hitting head on at 45 mph....is the same as hitting a wall at 45 mph. Not 90....not 22.5
From there differentials of speed xxx factor the margins.
