It occurred to me this morning to ask this here. For a short commute it makes sense to use your bike instead of a car but for longer distances, even though more gas would be used, if you have a gas efficient car, one might be better off using the car. Here's why: a longer bike commute requires more food and laundry.

Right now my meals are based on my activity level. When I introduce about 3 hrs of cardio I will b increasing my carbs and protein and that costs money. Food actually costs more than fuel. That combined with laundry detergent and hot water, and parts and nick knacks for the bike, add up to an equation that at the end of the season doesn't save me money.

Anyway I thought I'd put this out here for discussion, what do we think about the distance affecting the potential cost savings? I'm thinking that over 25 miles round trip there is no cost savings if your car gets 25 mpg commuting and gas is $2.00 pr gal.
