Ezra keeps the bike debate going:
...cycling in some countries is a demographically specific pursuit while in other countries, it's a broadly used form of transportation favored by substantial chunks of both genders, all age groups, and all income levels. The overarching point is simply that, in societies where cycling infrastructure is intelligently planned, there's nothing elitist, or liberal, or uncommon, about it... In America no one cycles, and when you're over thirty, really no one cycles. In the Netherlands, a quarter of the old make their trips by bike. Which is just to say, everyone cycles. It's like walking, or driving: A mode of transportation that's often the best for a given trip. Not some sort of radical lifestyle statement.
