Completely wrong. The bicycle is the single most energy efficient method of transportation to date. Several times more efficient than walking even. Compared to other vehicles, there really is no comparison. A gallon of gasoline has about 31,000 calories. In my car, that gets me about 20 miles, for 1550 calories per mile. A bicycle on the other hand consumes about 34 calories per mile.
Alright, now I wonder where I got the info I had before. I’m not usually wrong, and neither are you, so I had to go check my info, and now can’t back up my side of the argument. Damnit, i hate that. :)
