Right. Think of all the few times you might need to buy something truly cumbersome and bulky that can’t realistically be brought home via mass transit. Now, think of how much it might cost to have that item delivered - a service readily available in cities.
Calculate up how much a car costs, insurance, fuel, maintenance, and parking, and to be fair, subtract mass transit costs.
Compare that to the rare delivery.
See if you’re better off, saving money, not having a car.
On the rare occasion you do want a car for long-distances not practical by air or other transit, rent one.
Source: lived in a major metro area. Car was a real burden having the expense of it, parking it, and having to be on watch all the time for street sweeping or snow days where you couldn’t park on the street. The subway was cheap, accessible, and far quicker than driving the vast majority of the time.
