I think you are overgeneralizing from your experience. I grew up in the north woods of Minnesota, about 400 km from a large city. Although there are only two major roads that head in the general direction of the city, there are hundreds of small back roads, some of which can significantly reduce your driving time. In my experience, much of the rural US is like this, although there are some obvious exceptions that come to mind.

And what happens when they clone the MAC address of an unblocked computer (such as the parent's computer)? Bypassing filters that only block some machines on a network doesn't exactly require a genius.
