Well, now I'm really confused.
My Prius, and I think all Prii, came with little OEM wind deflectors in front of
both the front and rear wheels.
And as I understand it, these little jobbies are meant to start vortexes that
spin around the wheels and as you say, are intended to "manage the
pressure transition to the rear."
All well and good, and I think we're together up to this point.
From the article I understand that what then happens to the vortexes, after
the wheel is also important.
My question has to do with mud flaps that are installed behind the wheels.
