I'll bet if you drove 25 mph in your Tacoma and measured the MPG and then
bolted 4'x8' sheet of plywood vertically on your tailgate, you would see a big
drop in your 25 mph FE.
I believe that cd is important at low speeds too. (Just ask anyone who races bicycles).
If the moons help the cd at 120+mph and didn't help some at 55 mph, I would be very surprised.
It's not like they are active device like a spoiler or VG, to my eye, they are pretty passive.
Kinda like rolling up your windows when you drive over 30.. It helps.
