Bicycling has less economic density than driving. Compared to a private automobile, the total cost of operation of a bicycle is probably ten times less: “According to a 2004 American Automobile Association study, the average American spends $8,410 per year (roughly $700 per month) to own a vehicle.”

Now, if you were to substitute a bike for a car, that TCO expenditure might go to $70/month. You’ve saved a bundle! But what about all those folks in your local economy who were counting on you to spend $700/month? The gas station, the loan company, the insurance agent, the repair shop — what are they supposed to do?
