Once upon a time I used much the same reasoning as your last point to calculate the expected total change in quality-adjusted life years for reducing the speed limit on our local freeway to various points. I don't remember the exact outcome (although I'm pretty sure that reducing it below something like 80km/h was a net loss) but it was an interesting thought experiment to begin with, and it got a lot more interesting once I started getting angry responses to my results. :P
