Imagine a pedestrianish city like Venice. Now let's say we built a few sporatic side roads that kind of connect but don't really connect to anything and they are filled with potholes and trash and are semi-unsafe to use. Would you be surprised if you saw only a few people per hour using those roads? I bet if they started connecting the roads, building branches, and building parking lots the amount of drivers would increase exponentially. Sorry a little unrelated, but I'm a little tipsy :/
