Subscribed. If you include my daily paper route that I did by bicycle, I have about 5 decades of bicycle commuting experience. As the OP has stated “If it were easy, everyone would be doing it.” There are a number of design considerations that make reducing aero drag on a bicycle very difficult. Aero drag on a Battle Mountain streamliner can be very low but they are totally impractical to ride. A faired recumbent trike can strike a good balance between function and low drag but you add weight, length and perhaps some issues with visibility. Adding a fairing to an upright cycle can add frontal area in crosswinds. I did the bulk of my commuting with a drop bar bike which allowed several hand positions including getting flat and low when confronted with strong winds.

I look forward to your progress with this.
60 mpg hwy highest, 50+mpg lifetime
