Bike lanes: In some cities people are so desperate for them they’ll go so far as to mark their own. Here in New York City, it
feels like every time I get on my bike there is a new bike lane —
sometimes on the left, sometimes buffered, and sometimes completely
separated from automobile traffic.

I recently had
the opportunity to go for a ride with the NYC DOT bicycle boys, who
explained the classes of bike lanes and showed off some of these
inventive facilities.
