Everything the other people said, but also weird things with center of body mass and the strike area. You don't want people pushed under the car. You also don't want them to go head first through the windshield, which I'm told is why the Mini Cooper got such a drastic redesign a few years ago - they needed a taller hood not to flip pedestrians.

The tall grill at least doesn't ram your head through the glass. I don't know who started calling them FUVs (Fuck U Vehicles) but they are not wrong.
