My "special technique" is nothing new, just simple physics. The 1% of the time that I need fast handling I lift my back away from the seat, and the rest of the time I'm far more comfortable than I would be on an upright bike.
It is not a secret that the UCI banned Recumbent bikes in 1934 because they were too fast. Your statement above is just flat out wrong. You're pretty obstinate about this, but whenever you are confronted by a fact that puts your point of view in question you seem to ignore it.
Now don't get me wrong, I accept that many past recumbent designs have had unreasonable compromises, but if I have a main point here, it is that electrification allows the recumbent bike designer to solve those problems and create a truly useful vehicle. I think it's time for you to stop dredging up historical shortcomings of the recumbent position and accept that times change and problems can be solved.
My bike can carry 120 litres of cargo, has a 200 kilometer range, and is safe and comfortable on the side of our highways here in BC. These features make it a genuine car replacement, especially over great distances. My longest ride has been 250 km, and at the end I stepped off of the bike feeling no discomfort. That would not have been possible on an upright bike.
