I used to drive horribly fast on public roads - I didn't pass people at those speeds but still, not the smartest thing to do. With experience comes wisdom - and wisdom generally comes from the close calls and near death experiences.

Depending you where you live you've probably seen dead deer on the side of the highway. Now use your imagination.

Where are you getting this "inertia increases as a square of the velocity" stuff?

Maybe you are thinking of energy as in E = 1/2mv^2 i.e. twice as fast = 4 times as much energy?

I suppose if you go twice as fast your brakes will have to dump 4 times as much energy (heat) but I don't know if that will effect your stopping distance - which is a function of your tires.
