Oh I'm fully capable of doing it. I've handled a 100 mile each direction super commute before and I'm currently considering supercommuting again because my grandmother needs some help with day to day tasks and lives a bit away from me. But what I can do vs what I like to do are 2 very different things, and I'm simply voicing that I do not like high speed limits on roads.

The fact is the severity of a crash increases exponentially with speed (and your margin for error as a driver decreases similarly) and humans aren't great at driving cars, so as a human who generally wants to continue living, that's the fear in the back of my head on those high speed bits of highway where some drivers are very insistant on going far beyond the posted speed limit.

Oh and lowering speed limits is good for gas milage and therefore better for emissions. So there plenty of societal good to come from lowering speed limits in general
