I get a bit of crap on a couple of forums from time to time about aerodynamics and safety posts. It doesn't help my anxiety/depression disease any but I have pills for that. After many years of working with the public selling auto parts I have concluded that many folks are abusive because they are afraid of loss in some form. As a matter of fact since I started using a homemade fairing on my bicycle and obeying traffic rules I have had no one make rude remarks or gestures. I have had people stop and compliment my fairing often. Hopefully I can finish optimizing the design and sell plans online. I am polite and smile at people I pass when I can. In the movie "Harvey" the main character has a line, "I used to try to be clever. Now I am just polite; it works better that way."
