Twisted body panels around an intact cabin are not a design failure. They are the main safety feature in modern car crashes, turning metal into a sacrificial shield around a rigid passenger cell.
The logic is rooted in basic mechanics. A moving car carries kinetic energy that must go somewhere when motion stops. Crumple zones are built with controlled weak points and deformable beams so that steel and aluminum absorb that energy through plastic deformation. By stretching the stopping distance and time, they lower peak deceleration and impact force on the occupants, which directly reduces the risk of traumatic injury.
The passenger cell works in the opposite direction. It is engineered as a stiff safety cage with high-strength steel, load paths and cross-members that resist intrusion. While the outer shell collapses, this cage preserves survival space and keeps acceleration loads more uniform across the restraint system. Seat belts and airbags then manage remaining momentum, relying on principles like impulse and force distribution across the torso and head. The car appears destroyed because its structure has done the physics work the human body cannot survive.
