Question

How is the newer cars are more fragile during an accident but are more safe for the passengers

In: Physics

Answer 1

Crumple zones. Because moment is conserved in a collision, the more parts there are that absorb that momentum (either by deforming or flying off), the less the passengers do, keeping them safer. And inside that is a very strong cage around the passenger area that protects them from getting squished.
