    What sense would that make?

      Kinetic energy is E=1/2mv^2 and because of aerodynamics and friction factors, energy efficiency (or, consumption) varies a lot at different speeds.

      This graph has a nonlinear x scale because each vehicle’s entry is at a different speed, therefore the energy scale is nonsensical.

        The end result will be useless because you won’t cycle at car speeds and won’t drive at walking speeds, so the energy per km wouldn’t be realistic.

          Of course. But the way it is plotted now also gives a false sense of energy economy.

          Maybe there’s another way to compare the data.

          An energy-speed plot with multiple curves for the different vehicles comes to mind. Then simply stop plotting that curve when that vehicle is outside of its speed range.

          I’m not contesting the notion that the plot is trying to convey; just that it’s not really the right format for visualizing this data.
