Can Azazell chime in? Did he build any roads to City states or to connect cities?
I don't see how you can only be charged for a road inside one of your city's cultural sphere... seems pretty obvious that without culture bumps and with no distance maitenance costs, you could build a city a long way away. And Greg talked about road cost being an impediment to spreading out.
Either the initial construction cost is high, or the maintenance cost is high; other wie the incentive is to build huge networks of roads in neutral territory. And the realism factor, in addition to the gameplay factor, would seem low if the peasants in neutral lands were maintaining roads.
