On a related note, why is the rear end of a car built like a fortress, and the front end like an eggshell? I ran into a Kia, and there is a small dent in her bumper. My Mercedes' whole front end is smashed. The hood is wrinkled, the grille crumbled into hundreds of pieces, the light lenses and brackets are destroyed, the radiator got pushed into the fan... only the fenders and the directional lights were undamaged.
I understand the whole idea of energy-absorbing construction, but why does it have to absorb that much energy from a 10 MPH collision?
