If speed doubles, how does crash destructive power change?

Explanation:
Key idea: the crash power comes from kinetic energy, which depends on the square of your speed. If speed doubles, the kinetic energy becomes four times larger because (1/2) m (2v)^2 = 4 × (1/2) m v^2. That extra energy is what the vehicle must absorb in a crash, leading to roughly four times more destructive potential. Momentum does double when speed doubles, but destructive power in a crash is about energy, which scales with v^2, not linearly with speed. So the correct result is an increase by four times.
