Car-dominant policies are also exclusionary, just for a different group. Being effectively required to drive is an enormous burden on the impoverished.
Also it sounds like a mobility scooter is kind of what you want?
Mobility scooters don't work so well in 3 inches of slushy snow (unless they make them with wheelchair sized wheels?) In any case, my area swings from -5f and lower on the cold winter days to 105f+ on the hot summer days, so anything that's not climate controlled is fairly unpleasant. We just hired in some contractors from the west cost, and we're predicted to have 12" of snow on Monday, a full day of sub-0f on Wednesday, and a -10f night the weekend after. They're quickly learning a lot about West Michigan weather :).
