You've been busy. What are the relative merits for getting you message out, of Autospeed, your book, and videos on Youtube?
Trailing vortices and drag: You may get gentle rains and sunshine, but in the Pacific Nortwest, in a driving rain on the Interstate, you get a good view of vortexes. I like the trucks with lateral vortexes projecting out of the front wheel wells. Water has more mass than air which complicates things, but the water likes low pressure areas.

Vortex generators: I was hoping for fads or fashions in vortex generators. A few years back it was glowing plasma actuators.

Face the danger and row away from it.
