"Bicycles are the most efficient forms of transport in energy per mile. They are often the fastest in built up areas as well."
I don't disagree, but if this is the purpose of this graphic, why not just specifically measure different forms of transport in energy per mile?
This article is putting a metric of efficiency, while ignoring the reasons why things like a dog may have less efficent locomotion over perfectly flat terrain, because there are very few natural landmarks that have perfectly flat terrain.
I'd love to see a deeper comparison, how does efficiency of locomotion compare between animals within different types of environments, obstacles, etc. Otherwise this is a graphic that was used to make a point about cycling using an abstract measure rather than actual research.
