Perhaps because cyclists grow proficient making decisions at 40 mph (or more) balanced atop tires only 23mm wide they can *adjust* more easily to outside stimuli. Same thing is learned via rugged mountainbike riding.
The ability to regain balance, allow the mind to decrease speed, and not "freak-out" likely carries into other areas of life.
