Yes! I can completely relate. My bike commute to work is only about 3 miles, and I have train stations a couple blocks from my house, and directly across the street from my office. I also pay for an unlimited use combination subway/bus pass, and in 30 years I have never had a driver's license or car. But one day I thought, "I feel like buying a bicycle" and the next thing I knew I was riding through urban traffic to work. It's not a long enough ride to burn calories, I get to work uncomfortably drenched in sweat, and I've tossed out a bazillion dollars on the bike, a Chrome bag, helmets, lights, tools, tubes.... But it's fun.
