You all do realize that suburbs existed before the invention of the car right? American infrastructure is bad but it’s not irredeemable, the assumption that we can’t provide public transportation to these places because of a lack of resources is malthusian. And sure some places like the American Southwest and Florida are legitimately over human population carrying capacity due to climate change but in general the earth as a whole isn’t, and cities like Amsterdam are just as unsustainable as Miami since even though has one of those le epic reddit notjustbikes cityskylines approved infrastructure, both are below the sea level.
I think in general our message should be abolish the need to own the automobile, any measures meant to limit car use should target the rich before the poor. And that trains are good, and that a high speed train across the United States would be a rather popular project in the eyes of even the chuds. And by god stop calling for the suburbs to be razed, stop trying to be zoomer Robert Moses.
i mean, one of the easiest ways to get people to move out of those suburbs is for the cities they are attached to to stop subsidising every part of their infrastructure. I'm pretty sure it's one of the main recommendations that Strong Towns make, at least as far as NotJustBikes has presented it, since the suburbs are insanely expensive infrastructure wise. So if you just begin actually pricing in all the externalities that are currently being forced upon the places with active economies, then the problem will likely revert with decent speed.
