I don't consider it a "commitment" so much as a conscious lifestyle choice.
7+ years ago, I moved from a college town in North Texas to Chicago. I sold my car and now bike 99% of the time. I'll take transit, Lyft, or rent a car/truck as-needed. I chose to live in a neighborhood that was an easy commute to work by bike, and also had good transit accessibility.
Aside from the pleasure I get from riding a bike, I've saved over US$30,000 vs. owning a car. One of the best decisions I ever made.
