Safe drafting and impact on mpg

I've been wondering how effective drafting behind a vehicle is and if noticeable results can be achieved at a safe distance. Obviously, if I'm 3" away from the bumper of the car in front of me, I'm going to be utilizing their pushing of the air out of my way better than if I'm 100' behind them. But we live in a world where the unexpected happens and you can't safely travel 3" from the back of the car in front of you.

So, is there a safe distance that anyone has documented measurable efficiency gains by drafting leading vehicles?
