Hi Again,

There is some wake turbulence back there, though. I know this because I had a ninja motorcyle bike rider draft off my left rear by about a foot while I was running on level terrain in cruise control at 62 mph. And that improved my mileage, rather than decreasing it. The motorcyle and rider were apparently giving my car a psuedo boat tail effect, and probably smoothing out the side body air flow off the back of the car. This was good for about a 2 mpg improvement.
