All your Newer car have crumple zones
crumple zones absorb impact damage to protect the passenger cell
Crumple Zones prevent damage or injury by supplying a place in the structure of the frame to crumple in an accident.
Crumple zones are zones built into cars that crumple in a controlled manner. The main crumple zones are at the front and the rear of a vehicle. On impact, they crumple up in a controlled manner, which stops the force energy reaching the occupants and injuring them. The crumple zone dissipates the energy Advantage :they save lives by stopping forceful energy Disadvantage: they can kill occupants in severe accidents because in high speed impacts they can dislodge the dashboard from the frame of the body Potential collapse of the footwells, trapping the driver and passenger Crumple zones can be recognised by bent body panels.

You would have to crash to use them.
By absorbing some of the energy.
seat belts and air bags
crumple zones are not different materials, they are strategically placed indentions in the body panels. these indentions collapse on inpact instead of becoming a projectile into the passenger compartment.
not really. if you have efficient crumple zones and air bags, you will be safer. the crumple zones take away the force of the collision, and the air bags help you to not get whiplash or brain yourself against the dashboard.
