| http://www.w3.org/ns/prov#value | - With the square of the velocity.Ek = 1/2 * m * v^2So at notional velocities (speeds) of 20 units, 30 units, and 40 units, the kinetic energy of the vehicle (which has to go somewhere if there is a collision) is (20*20)=400 units, (30*30)=900 units, (40*40)=1600 units.So, if you double the speed (from 20 to 40), you quadruple the energy.This physical law also explains why even quite modest reductio
