> That's too bad. In the area around where I live I have yet to encounter a suburb that doesn't have sidewalks!
It’s often linked to ugly history: when we were shopping around here in the DC area, there were tons of suburban houses with no sidewalks and transit-hostile road design which were built right after the major civil rights wins, when the thinking was that most black people couldn’t afford cars.
> I understand what you meant by "walkability". I also don't think it's fun or practical.
My thinking is that it’s less about fun than barriers to activity and car-centricity. If exercise is something which requires traveling elsewhere or you have to do on will-power an awful lot of people won’t do it very much, especially over time (maybe they walk the exercise trail when they first move in but lose interest over time because there’s only one route and that gets monotonous, etc.). Having kids is eye-opening that way when you’re seeing where they can go safely and under their own power, not to mention parents realizing how long they’ll be playing chauffeur.
The car centric point I mentioned is related: cars are expensive ($11k/year on average in 2019) so when your household has purchased one per adult you typically end up treating them as your default mode of transportation, which over time degrades your body and conditions you to think of being outside of air conditioning as outliers, and cars are dangerous which further reduces your options. Kids are driven to parks 3 blocks away because their parents are worried they’ll get hit by a car; pedestrian routes are hot, noisy, and extra long; etc.
Obviously they’re useful too but I don’t think it’s coincidence that obesity has been going up as an increasingly large fraction of people live in environments designed to be used while sitting sedentary in a machine.
City living isn’t without its own problems but when you get 10k steps without even making an effort to exercise it helps.
