Yeah, same in Chicago, really the same as mass transit anywhere: You need density to make it work. My little town of under 100K population tries to do city bus services but it's a joke. Most routes run once or twice an hour which is not often enough to be convenient. Busses drive around empty or with one or two riders. It's a service that costs millions of dollars a year to operate and is used by a tiny minority of the people. It's a sacred cow though.
