I'll admit it, I do. My primary reason for doing so is time away from my family. I can leave early early in the morning and get plenty of riding in (who says I have to ride straight to work?) and then still have a reasonable time back to the car. I ride ~19 in the morning, and 9 back to the car. Driving 15.
I look forward to the day where I don't need my car, don't own one either and can still work!
