US pedestrians die at a higher rate than elsewhere but not because you have a lot more vehicle miles, it's down to the appalling quality of the roads (design construction, and maintenance), the shockingly casual attitude to drinking and driving, and the fact that so many US vehicles are pedestrian hostile.

But all of those things seem to be an expression of the US majority way of thinking. That is what needs changing; if you don't pedestrians will still be run over by drunk drivers, etc.
