Best speed for best milage?

Here's an EPA (U.S.) guide on fuel economy:
http://www.fueleconomy.gov/feg/FEG2004intro.pdf

There's a graph in that document that indicates the best mpg will be
achieved at a speed of 45 to 55 mph. That's probably the standard
government line, though, not taking all the variables into account.
You can also get the standard EPA mpg figures for U.S. cars of various
makes, models, and years at that site:

If you are rear-ended doing 50mph in a 70mph zone, you will
learn that you haven't considered 'all' cost factors when
computing the most economical speed.

I really dislike being pushed through unfamiliar cities when
traveling and try to avoid being in such situations at peak
travel hours. I find it's best to try to stay out of everyone's
way and not impede those who 'know' where they are going, concern
myself with staying alive, and worry about fuel economy when I'm
back on the open road.

I would hope most drivers would agree with this and be tolerant
of those who are 'unable' to face this fear factor due to age,
experience etc.
