I think that today, the most salient evidence of two cities belonging to the same community is an existance of commuters. So, Scania is too big to have a true nationalism, regionalism. We might eg. Even the prices of travel can set the size of the community. Let me finish with to say that in argicultural areas, people are less keen on moving, so therefore we have smaller communites.
People can sense the belonging to a community.
And this is really the speciality of the national state. Here, this idea is driven to its final point. Again, the Basque country is a good example. I'd say not. There is no possibility.
