Congratulations on "having a thought" while in class, especially havin a thought that isn't quite in line with the values of Driver's Ed. I bet that doesn't happen to some of your classmates! Your thoughtful and questioning attitudes give me hope for the future.

I agree that carfree transport will almost always save you money. If you have a car, each bike trip will save you a little money. Commuting by bike to work or school might save you more than $500 a year, for example.

If you don't have a car at all, the savings will be enormous. Going carfree will potentially save you more than $5,000 a year, or a quarter million dollars over your lifetime. You'll also be doing a lot of good for your health and the planet. Man I wish I'd put aside a quarter million dollars for my retirement. With good investment, I'd be a millionaire by now.

Now I'd like to ask you a question. What, if anything, have they taught you in Driver's Ed about sharing the road with bicycles?
