Good point on the authors oversight. I'm a big fan of WikipediA, and suggest you add a section whenever you see a section missing. The markup is very easy to learn and the "edit this article" is the only link you really need to worry about.
If you have any reservations about it, just send me your suggestions and I'll post to WikipediA verbatum.
PS.. Also check out the article on
Hypermiling I introduced in
this thread.
