Not saying they don't exist, just that it's extremely rare to see. I live within sight of a popular path/course and can say that I've only seen it a handful of times- generally most appear to be commuters or part-time (overweight or with kids) riders. You never see it within a group, which leads me to point at the "me too" mentality.
Keep in mind that I do live in Los Angeles and appearances are everything. Your results might vary.
