Considering that crashing a car at 248mph seldom ends well, Bugatti created a complex systems of structures and substructures for its Veyron supercar that serve and protect better than the LAPD.
With an eye toward driver protection, the car's development team created a "survival cell" monocoque shell in high-strength carbon fiber, which is thre times stronger than steel (but like 100,000 times more expensive than diamonds). The cell is fused to front and rear sub-frames, providing a degree of body rigidity double that of most modern sports cars. What's more, the doors are built using a system of metalwork covered in an aluminium skin to absorb impact and prevent penetration by sharp objects (like a 248mph guardrail), "crash claws" around the locks ensure forces of a collision transmit to the entire passenger structure, rather than collect in its weakest segments.
