We've also brought this approach to our buses, and uh you know, New York City has the largest bus fleet in North America, the slowest bus speeds. As everybody knows, you can walk across town faster than you can take the bus. And so we focused on the most congested areas of New York City, built out six bus rapid transit lines, 57 miles of new speedy bus lanes. You pay at kiosk before you get on the bus. We've got dedicated lanes that keep cars out because they get ticketed by a camera if they use that lane, and it's been a huge success. I think one of my very favorite moments as transportation commissioner was the day that we launched Citi Bike, and I was riding Citi Bike up First Avenue in my protected bike lane, and I looked over and I saw pedestrians standing safely on the pedestrian islands, and the traffic was flowing, birds were singing -- (Laughter) -- the buses were speeding up their dedicated lanes. It was just fantastic. And this is how it looked six years ago. And so, I think that the lesson that we have from New York is that it's possible to change your streets quickly, it's not expensive, it can provide immediate benefits, and it can be quite popular. You just need to re imagine your streets. They're hidden in plain sight.
