> The engine in any normal car is totally incompressible This is just an interesting aside note, but my mother was recently involved in a frontal collision while driving her 2016 hyundai i30. In what was approximately a 60-70 kph impact with another car, it was enough to shatter the aluminium engine block in several places, and the engine sort of crushed flat. I'd never seen a block do that before, at least not in a relatively low speed collision. Wish I'd taken some photos of it. But it made me wonder if modern cylinder block design incorporates any failure points in their design for such a scenario... Of course maybe it could have just come down to the randomness of crash dynamics.
