Auto makers spend ***** load of money testing and improving their cars. Check out these pictures of a very high speed collision (car hits a lorry from backside at 90+ mph).






This was a BMW M5 E60, RIP now.
Ofcourse, rich auto makers spend a lot more to keep the passenger cabin safe from impact, that is why the front and back of their cars are designed to absorb as much of impact as possible.

Our average Civics and Corollas are not designed in the same way sadly.
Best piece of advise, keep out of harm's way!
