I commute about 15 mi. one way. I drive to work with the bike on a rack. I bring a change of clothes for the following day as well as my bike clothes. At the end of the day I put on my bike shorts, put my keys and wallet in my seat pouch, and ride home. The next day I ride in, and I have clean clothes waiting for me. I like having the car at work in case I need to get to a meeting, I also like riding without having to carry a change of clothes and a briefcase on the bike. I'm lucky enough to have a rail line within a few blocks of home and work so I can take the train if it is raining/snowing too hard in the morning. I've thought of using an electric motor accessory, but I don't think I would like the added weight, and for the length of my commute it isn't necessary.
