This is pure trolling and has nothing to do with the article.

It purely was looking at the cost in fuel of go a mile compare to other transport.

Be it across a current city, desert or large dessert.

I'm not trolling. This kind of analysis is frequently trotted out to argue against transit, cycling infrastructure, and even sidewalks. Take for example this (totally moronic) post at the Freakonomics blog:

It's an anti-transit argument based entirely on energy per passenger-mile traveled, which is only relevant if you think a passenger-mile is a good thing which should be maximized.
