I remember a contest when the first Honda Insight was available, one of the teams use a Ford Excursion, and they opened up the back completely and put these wooden boards underneath it to divert all air away from the vehicle. Then they made a trip while drafting super close to the Excursion. On a car rated at something like 50mpg, they ended up getting 150mpg. On the highway wind resistance is huge.

For large values of one, one equals two, for small values of two.
