Shade Tree,
hate to derail an aero thread but Frank is right
at .35 Cd - and mixed driving - aero is not your first concern
(if you were long hauling at 75mph - that would be different)
look for a draggy break set up or mechanical issue
air up the tires and coast a bit - drive mello

then come back to aerodynamics - but don't expect much
aero is finesse and many mods with many small gains
better just to sllooowwww down
I would bet 40mph is your sweet spot - based on CAFE standards
instrumentation (scan gauge etc.) is very helpful

and way easier than a driving backwards
