Brings up the question if aero blocking panels should be flat or concave golf ball style.
I know mythbusters did an episode where they dimpled a Taurus and saw a hefty gain in aero effecienCy
My hood roof and trunk are covered in pea size hail damage.
Comparing my logs to other cars that is the only advantage I can think of and how I can average 39mpg on a bad tank in the city

*Dimples trigger a transition from laminar,to turbulent boundary layer (TBL).
*On any given day,if there's any wind at all,the Earth's boundary layer will turbulent and up to half a kilometer thick.
*So basically your car is already immersed in in a TBL by 20-mph and doesn't need any dimples to get as good of an attached flow as it can.

*If the hail damage IS improving your mpg,it's because it's acting as crude vortex generators (VGs).
*If so,properly sized and placed VGs near the back of the greenhouse would be all that was needed for the same effect.
