[DMCForum] bent impact absorbers, Re: Tech Session...(Joe O'Brien)

["twinenginedmc12" <twinenginedmc12@xxxxxxxxxxxxxxxxx>]

Hi VB.

Getting rear ended in my Delorean is one of the least of my worries.
I'm a lot more worried about frontal collisions.  And the foam in the 
impact absorber is already elastic, and does return to its original 
shape, just like you said.  I guess the designers like your idea too. 
I don't get that pillow thing, though.

Rick.
