It’s more convenient to own a car everywhere. Even in anti-car cities like NYC, London, and Paris, it’s still faster to drive to majority of places, they’ve just priced the majority of the population out of using a car. You won’t see the rich on the train in those cities as they’re all in chauffeured SUVs.
American cities are orders of magnitude more convenient than other countries’. It’s amazing that we can go from anywhere in the country to anywhere else in the country without doing anything more than typing an address into a computer. No schedules, no connections, privacy, and comfort.
Giving that up because of “muh carbon” or a childish desire to live atop a shopping mall is dumb.
Also, transit is far more expensive than owning a car, it’s just that someone else is paying most of the bill for you. Road infrastructure is orders of magnitude cheaper than transit infrastructure and is mostly funded by its users.
