I started bike commuting to work last September. I would drive half way and then ride to work. One day I rode the entire distance and it took me 15 minutes more to do the entire distance. The extra time it took to for half the commute was having to unload the bike, put on bike shoes and panniers. I would ride 4 -5 times a week.

Now I ride the full distance 3 times a week (MWF). On Thursday and one day on the weekend I do a group ride. The group rides have improved my riding ability and the social aspect is nice making it worth while. I hoping that next year I'll commute more, but there are times where I need to drive because of other requirements. I can't commute year round because of the weather. I'm not going to ride in the traffic lane with icy roads.

All this to say, that commuting makes my drives more bearable. I know I'm driving either because it is a recovery day or some other requirement that prevents me from riding.
