How can mv and mv² explain the damage "equally well", when one is linear and the other is quadratic with respect to velocity?

The point is the extreme magnitude of difference between a car and a bike/person. This shows it just fine.

Momentum is always conserved. Energy is partially conserved. If it squishes, it will be more like MV, if it bounces, it's more like 1/2 mv^2.
