I think on a caloric basis, it's still "cheaper" to ride, as you say.

But the question isn't one of ecology or conservation, it's one of economy. Which is cheaper to the end user?

I know I introduced a bunch of variables into it in earlier posts, but the most simplistic approach is the above question. Each further measurement just serves to add complexity to the equation, but proves that there is a substantial impact from either source, while showing how the question could apply to anyone, not just someone.
