Has anyone thought of doing an aerodynamic bed cap that starts halfway down the rear window instead of at the roof?
The benefit would be that if it starts below the sightline of the mirror, the driver's rearward view is not obstructed.
On the other hand, the driver's view downward and to the sides would still be blocked, which matters more the higher the vehicle is.
Would airflow reattach after the short step down from the roof?
How much better would it be than a flat tonneau?
