Also, following a truck will increase your mpg.

And not because of the lower air pressure zone behind the truck; you have to get dangerously close for that.

Truckers spend a fuck ton on fuel, so they have a huge vested interest in driving efficiency. My highway mpg rating is 27mpg, but I got 38mpg on an hour drive by chilling a safe distance behind a semi. It only added like 5 minutes tops to my trip.

Exactly. Similar to how others responded to a similar comment to yours, there isn't much slipstream savings without getting into the danger zone of around 30m (100ft), which you can't get with 3 second gaps at speed.

But you do get more fuel savings from driving at that slower speed, and from coasting and accelerating lightly/cruising. It perplexes me why people alternate gunning it with braking so much on the highway.
