These rules apply to racing bikes, not to bikes that are used everyday for commuting or recreation. If recumbents were so much superior to the classic diamond frame, they would dominate the non-racing-bike market. I rode enough recumbents to prefer my uprights when commuting in a city, also for mountain biking and rides through hilly areas. If a was commuting in a flat area outside of a city I would maybe consider a recumbent.

A recumbent isn't "superior" to a traditional frame. It has select improvements, but for the general consumer the ride quality of a traditional frame is much better.

The general consumer has never experienced a recumbent ride. If they had, they would find the recumbent more comfortable on longer rides.

For bumpy roads, you can always stand on the pedals on an upright bicycle and use your legs as shock absorbers. You can't really do that on a recumbent.

But the general consumer most likely doesn't want to spend too much money on a bicycle and recumbents tend to be a bit more expensive compared to uprights.
