You know, every time I see a recumbent, I look at the rider to whether it's just like the previous rider--a middle-aged white (or should I say Caucasian?) dude. I think I saw a woman on a recumbent once. Yeah, a lot of them have beards. And look long-haired (in the sense of Bohemian) or professorial.

Same phenomenon with Corvettes, except not as professorial-looking.

And yes, I'm sure there are lots of exceptions.
