Funny thing is - despite whatever some ass might tell you about truckers "feeling" parasitic losses from tail gaters... There is a very slight aero advantage when there's someone behind you as their high pressure fills in your low... Of course, someone in front is better - someone behind is okay - worst possible scenario is no one around you...

In fact, iHPVA rules state that chase cars must be at least 200' (not 100% sure on the exact number) behind the HPV on the course due to this advantage
