But 120mph is pretty fucking ridiculous. Except, that's a head on collision on a 60mph road.

Incorrect, for two reasons: 1, kinetic energy is proportional to the square of the speed. Twice as fast, quadruple the energy. 2, in a head-on collision, the crumple zones of both vehicles absorb the energy. I doubt the concrete pillar absorbed much.

The MythBusters did a nice episode on this.
