Unlike the approximate draw that I presented in my long 4$$ post. So by bicycling we're actually using as many or more fossil fuel calories compared to driving at the same speed. Otoh, everything I stated in the last post holds true if the car is going ~50mph and the cyclist ~15mph... Unfortunately I don' think most people can spend 4-6hours a day commuting.
