Better to have a simple piece of Coroplast making a nice radiused curve from the rear axle area up to and flush with the lower edge of the rear bumper, with flow fences if desired.

Pretty sure a large corporation like Honda with easily millions of dollars in resources and R&D know-how is going to throw on a "worthless" aero part on its flagship hybrid car. Those kinds of things cost money. Car companies will skimp on pennies if they can. For something as significant as that part, I doubt it's useless.
