How can I achieve max MPG with a little help

Strange question for an even stranger purpose.

If I wanted to draft behind a vehicle for maximum MPG gains under controlled conditions what would be the ideal shape of the object in front of my vehicle so I can draft it at a safe distance?

I hope the question is not to confusing ...

Some show (might've been mythbusters) built an extension on the back of a trailer that stuck out and and empty, then they pulled a honda insight up in the back inside of the little box. I figure that's pretty good.

Yeah, if you can fit somewhere that won't interfere w/the wake of the vehicle in front of you, you're essentially in a vacuum.... most efficient place to operate would be in a vacuum where the engine could still get as much air as it needs without sac'ing VE.

A flying brick wall with a Kammback that fit around your car would most likely be best?

Something with a low bottom edge. Semi trucks are bad for this. Tour buses are better.

I agree about the Kammback part, too. Basically, build a box and drive your car inside it.

The bicycle land speed record guys ride almost inside a truck.

Here's the video :

The low bottom edge is right on the ground, and the lead vehicle upper edge is upward.

So the questions begs, would it be considered cheating to attempt and beat that mpg record by using a pace car similar to the one bicyclists use? You technically are not modifying the car attempting the record, just giving it the best shot.

Is it cheating using steroids? I mean, everybody supposedly uses them and they are natural?!
