Those things aren't really equivalent though. The percentage of pedestrian deaths in a collision at given speeds is starting from a 100% rate of incidence. So whilst it's predictable, it's not necessarily probable. How many pedestrians is a driver actually likely to hit driving at 40mph? Generally speaking, zero. How many people is a lunatic swinging golf club likely to hit in a crowded club, quite a lot more than zero.

Nevertheless, I appreciate your point. I was thinking only of speeding on highways. Speeding is an issue and shouldn't be minimised.
