Re: [DML] crash tests / safety



I agree, rigid barrier tests 'ideally' result in the same KE loss and 
deformation forces as a 'balanced' head-on collision.  So a 40MPH 
barrier test would be the same as two Delorean's colliding head on 
while both are traveling at 40 (in which they would both crumple-a-
bit and come to a complete stop).

I think the primary difficulty with automobile safety and testing is 
the disparity in bumper heights.  These barrier tests assume that the 
bumper will be the interface between the two vehicles, which in 
general is not always the case, and certainly not always true with 
the Delorean. (I think about that every time I am sitting at a light 
and looking 'up' a truck's bumper).

But if you look at the footage, the results don't look that bad.  
Remember that the really telling bit of data is deceleration forces 
on the occupant (hopefully far less than what the car went through).  
It would be interesting to find more information/analysis of these 
tests.

stop dead, same as if one of them had hit a fixed wall instead of 
another car of equal weight coming from the opposite direction at the 
same speed.
