I would be very curious how much "flapping" would occur at speed with all the tractor induced turbulence. I'm sure there would be an improvement of sorts. I doubt State of Florida would approve or understand this "energy conservation device", its design leaves a lot on the table with incompleteness in its coverage, and I can't imagine the liability that exits if road debris or fatigue causes it to separate or be dragged behind like a moving banana peal for the following vehicle.
Other than that, I like the effort.
