But the crash from the car wreckage was not like that it, had front and back damage meaning it spun so the force was not sudden like in the vid and that it was a lesser impact.
And kinetic energy = 0.5mv², so a car travelling at 60mph will have 2¼ times as much kinetic energy as a car travelling at 40mph - that's plenty of scope to have the equivalent of a 40mph crash at one end, a 40mph crash at the other end, and some left over for the sides.
