That's definitely a habit you've formed, that you can grow out of. Given no choice, you'd quickly figure out optimized way to do the same things without a personal car.

Given proper public transportation, I did. Not owning a car is not only a lot cheaper, it's also quite liberating: - I don't fear I'll wreck it, or worse, I'll badly injure someone in a car accident - I don't have to drive and be angry about other people on the road, like a lot of drivers - I'm not owned by my car, that requires maintenance and cost beyond just running it. - Not fighting for parking spots!
