Would this not net me FE gains on the back of an SUV? Or are you simply saying that I should try to do better because I can?

AT Dynamics' Trailer Tail is designed for collapsability and minimum displacement when nested against the trailer.It's way out ahead of nothing,aerodynamically,but is intentionally compromised for operator ease of operation and also DOT length limitations.
My rendering comprises the most complicated geometric structures as far as fabrication goes.There's not a flat surface anywhere and the subtle curvilinear contours needed for boundary layer protection are everywhere.
Kamm's last project has this complex form

Tou can see how NASA went gently into the 'slopes'

I took advantage of VW's existing curvature when I did my Transporter

These curves are very important to the boundary layer.
