How much energy does a human use when he carries a car for a mile?

  I'm curious how I could have better phrased my comment so as to not invite responses like this. I guess I realize that 'efficient' vs 'effective' is a quibble, but I was trying to respond to the ambiguous usage of 'efficiency', not trying to give the final answer on the comparison.

    Sorry, I realized you were trying to be circumspect, I just was instantly visited with a vision of a guy trudging around a track with a car on his back.
