I had not thought about that issue. Do you think it is a serious error inducing problem? Hard to account for I suppose. If one baselines about the same time of day on the same road section, then the net impact on the percentage improvement, if any, would probably be small - maybe
If not an interstate, then we have to look for a 4 lane section of a blue highway I guess, but the problem doesn't necessarily go away. There is no way to maintain any stable test speed on a two lane.
The only infallible way is a wind tunnel. Maybe someone can find an aeronautical engineering grad student, with wind tunnel access, who needs a thesis subject
Maybe we can copy the Wright Bros. low speed tunnel where the reynolds number isn't much different.
