> millennials who’ve rejected suburban life to go car-free or car-light in the city
I'm one such millennial living car-free in Boston. I would gladly move to the suburbs if I could complete all my ordinary day-to-day tasks (commuting, grocery store shopping, hitting my favorite local restaurant, etc) without touching a car. But the fact is, aside from the commercial/residential zoning divide, having these stores in walking distance is not economically feasible without a certain level of density that American suburbs just can't fulfill. America's strange obsession with big lawns and single family housing has shut down the dream of living without a car everywhere except for the urban cores of the few top metro areas in the country. Furthermore, this dispersed suburban housing style is enforced by local zoning ordinance (& requires supermajority of town vote to change zoning rules in the state of MA)!
