ultra low profile sedans and rotary engines are the most evolved cars, so why do we have trucks? or more on point, road bikes are more efficient than mountain bikes. The monolithic view that a bike is about putting energy in and getting forward motion on a flat road out, misses the multirole requirement of a bike. Just as saying humans are unevolved because we aren't the fastest animals in the animal kingdom. Bikes, like humans have many challenges other than just getting from point a to point b. sometimes we have to stop for short periods following traffic patterns. I suspect rolling onto the pavement each time will get old fast. More on that surface, bumps and jars from imperfect road conditions being solely absorbed by my laying down bits seems pretty awful. Being able to see those upcoming obstacles and potentially avoiding the more significant ones, is likely important.
