Looking at it from an energy point of view, in the two-car head on collision there is twice as much energy at the time of impact, but there is two cars involved so there is twice as much body work to absorb that energy. So each car still only has to absorb the energy of one impact with an immovable wall.
The crumple zones and time period of the accident are doubled to counteract the doubling of speed and energy.
