Cars or trucks with poor aerodynamics or large frontal area it will help economy with thin air. The problem is it is also usually colder at higher altitude so it probably is a wash. Pilots have to consider such things, it think they use density altitude to figure where they are in relation to standard atmospheric pressure.
