Its said that cars are “weaker” because they’re now made from a softer material proper to receive impact, thus providing safety to the driver. How will safety work with cybertruck’s 30x ‘ultrahard’ stainless steel when crashing?

Answer 1

Rigid is dangerous, basically what you are interested in is a deceleration force (basically g force) if you stop from 30 MPH in 1/1000th of a second your body is subjected to a huge deceleration force and it can kill you if you have the same impact over 1 second then you are likely to survive. The crumple zone of the other vehicle really isn’t what is saving your life here, the only extra risk with the crumple zone is if bits of the vehicle are pushed into the passenger space.
