The risk of pedestrian death in a collision goes from about 10% at 25mph to over 50% at 40mph, and this level of speeding is absolutely normal in the american city I live in.

A pedestrian dying because of a driver's decision to speed in this way is predictable, absolutely expected. Shit I doubt my odds with a golf club at a party are anywhere near 50%. So why is one violence and the other not? I think only because we have decided it is not. But again that decision is exactly what I'm challenging. Calling it silly is not a convincing argument to me.
