Physics again. Head on subjects the passengers to different forces than being hit from behind. In a front end, the car(s) stop, but the passengers keep going until they strike dash, windshield, etc. (That's why seat belts & air bags.) In a rear-ender, you are (with luck) pressed back into your fairly form-fitting, supportive bucket seat by an acceleration of several dozen G, which is quite survivable.

Should be fairly easy to think of "egg in a box" experiments which demonstrate this. After all, why are eggs sold in flimsy cardboard cartons which cushion each individual egg, instead of loose inside strong metal boxes?
