Most places where parking costs that much are places where having a car is borderline unnecessary. I kept my car when I lived in NYC but mostly because I didn't expect the experiment to work out, and it made sense to be able to just pack up and leave for my house in Alabama without having to buy another car. Between insurance and parking, I was paying $3-400/mo for the thing to rust on the curb and get repeatedly broken into.
If I ever went back to something like that, I'd probably sell the car.
