I have read about this sort of thing - reattaching flow and such.
So as an extreme example, when you have a tailgater 'drafting' behind your ultra slick car, he is actually ruining you aerodynamics by following too closely ?
You are pulling him in your wake, and if it is a large SUV then he just ruined your aero big time.
( In this case, it you might end up getting better MPG by driving 85 MPH and not having a string of SUVs in you wake ... right ? )
So if I drive a Hummer and had an Aptera tailgaiting me, then the .Cd on the Dummer would go down as well since the flow would reattach onto the Aptera ??
