Its not the first time I've heard of them lying.
". Obviously you don't see how it works properly "
Obviously.
" but I'm pretty sure they'd find a way for that not to happen."
I'm not. You can't fit a 3 foot engine into a 6 inch space. Its physically impossible. Besides, why would you want to do it?
You mentioned earlier that it would increase crumple distanced but this would only be the case if you forcefully ejected the engine out. There simply isn't enough time for an engine to completely fall out by force of gravity in the fraction of a second that a crash takes place. That fraction of a second is the only time when a large crumple distance would be of any use.
You'd have to have something that could forcefully eject an engine block(and those suckers aren't light) in a fraction of a second and I just don't think that that could be feasiably done. At least not in a commerical car and without great risk to the driver. Not to mention that whole issue of space.
Sorry man. I just don't believe that it can be done.
