Good point, but just rounding the corner edges to the optional roundness isn't the same or effective and a whole body approach that includes a massive roof top faring.
No one is going to claim that a cube with radius edges is as aerodynamic as a teardrop shape for instance.
He has one good detail on the truck, but as a whole it is flawed in every way possible.
It makes for an excellent ecomodder challenge though.
EDIT:
Look at the big rig fairings I posted, if just rounding the edges of the tractor trailer boxes was truly optimum then why would anyone strive for a better fairing?
