The miles per dollar analysis ignores the huge upfront cost investment in a motor vehicle, the huge annopual insurance and maintenance costs and the fact that you will still burn calories while driving.

In fact, most cost-per-mile analyses assume you're cycling briskly. You can lower the caloric consumption per mile by simply cycling slower and more effectively.

I once spent an entire year walking several miles a day to school, and my typical Western-style diet had so many excess calories in it that my food costs didn't increase at all, which saved me a pretty bundle in commuting costs. And walking is much less energy efficient than cycling. Also terribly time inefficient.
