roger - Perhaps I wasn't as clear as I'd hoped to be.
I know that our states are not nations. I know that if we want to compare our states to political entities that are the most like them, then your example of the Cantons of Switzerland is a closer, better analogy. But that was not my purpose.
The reservation expressed was that separate states each building their own roads wouldn't work out well as a total system. I
specifically chose an analogous situation where the differences between the entities was greater than that between our states; the nations of Europe.
I agree that the analogy is imperfect for the use to which you wish to put it. I hope you can see that yours is not the purpose I had in mind, and that for my purposes it works just fine.
