Sidewalks and 15-25mph speed limits go a long way. Would be nice if there was little community stores for staples embedded in the neighborhood, but that's a foreign concept in American suburbs
It isn't there because of zoning practices separating living areas from businesses, which is often decided at the local level. Just gotta convince all your neighbors that they should be good with it too....
Be sure to add side walks with it. My childhood neighborhood now has a little strip mall with some snack shops. They are nice, but no safe way to walk to it. Short walk, but still.
It is simply an example of the opposite of a walkable neighborhood/community, literally framed at such an angle as to capture the ludicrousness of it.
It is an illustration of the absurdity of car-brained NA city design.
But it isn't exaggerated.
These kinds of developments, neighborhoods, are absolutely everywhere in the US, they are very common.
Even the use of 'walkable' may noy be satire: If there are sidewalks the whole way, well that would actually be uncommon, and many US policy makers and local city urban planners would actually, seriously, class this as walkable.
I am guessing folks from more civilized parts of the world are reading this as satire, because this seems unfathomably, beyond belief stupid.
