You do realize that the streets in Brooklyn were laid out over a century ago when much of Kings County (this was pre-merger) was farmland, and even in urban areas (downtown Brooklyn was already urban), few people owned private vehicles.
The obvious solution is to tear down most of the houses and replace the people with cows and horses. If one can’t stand modern traffic, move to a remote suburb, or at least a city that was laid out after the invention of automobiles.
