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.
I agree with exactly what otto said in response

I love it when I hear someone say that semi truck drivers can feel people behind them because it puts more aero drag on their rig.... And by love it, I mean it makes me laugh and disturbed that disinformation is being shared...
Cars have not created a new problem. They merely made more urgent the necessity to solve existing ones.
