Only thing is that the cycling infrastructure takes up a lot less space. You can move an enormous amount of bicycle traffic down a 8 foot lane. Probably the equivalent of 6 car lanes. Also think about the parking infrastructure. You can fit about 20 bikes in a space reserved for cars.
I know this because if you visit my downtown, you'll noticed that every second building is a car park.
