Some truckers are "air heads". Tonight along a 20 mile stretch of
interstate I watched two truckers "spend all night" passing each
other. It seems that when their respective truck was behind the other,
the air resistance got less due to the other vehicle "shielding" it.
So the trailing truck picked up speed and then passed but as it got
out in front it slowed and got back into the right lane and could not
maintain a speed to pull away. Then the other truck now was "shielded"
and this truck then passed and the whole process was repeaated again
and again while blocking dozens of other vehicles from passing for 20
miles, most of the time.

What "air heads"! Most truckers know if you stay behind the other guy
you can save a bit on gas. And if you cannot maintain the speed up
front (like when your vehicle is empty) then passing an equally loaded
truck with the same engine power will get you nowhere.

In Europe a trucker who cannot pass and maintain a faster speed could
get fined hundreds of dollars. In the USA, all they get is angry
drivers in cars.
