>Their logic seems a bit wonky. One car hitting a wall at 120 is not the same as two cars hitting each other head on at 120. Wouldn't the car have to do 240 to simulate that ?

No. 1 car hitting an immovable object at 120 takes the full force, however, 2 cars travelling at 120 (assuming similar mass) would disperse the force equally between them, thus they would both take the equilivent of hitting the wall at 120 not 240.

>In practice I'd guess a combined impact speed of 120 is *very* rare. Usually one or both drivers has braked pretty hard before the impact - the 40 mph test is probably a truer reflection of what happens in reality....
