These are some really great answers! I own a car and really do enjoy driving it, but I do not enjoy the stop and go traffic, which occurs while going to work. Riding is much more enjoyable. Also, since my trip is only two miles, the car doesn't even have a chance to fully warm up. Such short trips are hard on cars.
Plus I feel much better with the consistent exercise! Additionally, if I can get to work without having to pay for gas, I will.
