I started working out because I was super weak and just had a kid, and I realized there was a legitimate risk that I wouldn't be able to pick up my own child, so I started doing some strength training and holy crap this is amazing. Then I went back to college and lost my workout schedule, but after college I started running the following super smokey summer and didn't make much progress, but this summer I've picked up biking and I'm currently up to about 3 miles of extremely hilly biking every day.
I seriously forgot how fun biking is, and it's also nice just how much healthier I feel from the regular fitness
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
