Since you asked, to support your contention that educated people cycle-commute, I'm a decades-long, year-round, cycle-commuting pathologist at a suburban Boston hospital, with an MD degree and board-certified in four specialties. I do admit that many at work call me crazy, but I’ve also been called a saint.

My hospital is an ideal destination for a cycle commuter. I bring the bike inside near my office, and have a place to hang my cycling clothes and a table fan to dry them off. For the most part I wear surgical scrubs all day so I don't necessarily have to clean off on arrival (I shower at home before the ride). I do have shower facilities though, as well as a coffee shop and cafeteria on site. Finally, almost all my personal service needs like barber shop, dentist, dry-cleaner/tailor, supermarket and drugstore, and good take-out restaurants are all within walking distance, or a short hop on the bike.
