Drafting is effective - geese do it, squadrons do it. In 2000 an editor for Car & Driver poked inches behind an Explorer with a plywood board blocking better than an 18-wheeler....at 58mph on a warm day I might get as good as 85mpg, but he got 121mpg. Two years ago I noticed a 7F rise in coolant temp. I don't do it anymore - ever.

Hypermiler-bashers are doing their darndest to say drafting semis is standard procedure, but I have yet to know of a hypermiler that has done it the last 1-2 years. At Wayne's site we empatically discourage the practice. I've lost count of hypermiling articles that at the end have it advised against by state trooper that likely have no clue to hypermiling and some articles are simply and OP/ED against it posing as reporting with wild accusations of hypermiliner doing rolling stops, pulse and glide in rush hour traffic, etc. If you took them serously, we are up their with sucide bombers, but wait a minute. If there was ONE accident that could be linked to hypermiling, it would be news, yet 100-110 Americas die on the roads due to speeding, DUI, distraction, recklessness.

There is too much traffic to do this in urban areas long enough to benefit significantly. Now that truckers are aware, many will vary their speed, etc to shake tailgaters off.

Anyway, please make this an illustration that it's effective but not recommended.

If you want to reduce wind resistance, aeromod.
Have you looked at the hypermiling board? People do the rolling stops, etc etc
