Only if you don't value your time. Either you're paying even more for taxis and rideshares than you would to own your car, or you're spending an hour on trips that would take 10 minutes by car.

I think it's actually faster to get to central London from me on the tube than by car, not even counting looking for parking. And hell, on the tube I can read, listen to a podcast, code, or even call family. Can't do most of that in a car.
