I was recently visiting the Magdalensberg (Noreia)
http://www.unrv.com/roman-events/magdalensberg.php
which is far away from Rome however it has everything rome had, just smaller, so i believe life was even in smaller places way ahead of its time, to add to that the life of the celts there was far from being barbaric or "dark age like" but had their own "civilisation" built over hundreds of years and just adapting to the roman life style..
Lots of the busts there show that while the man were dressed, spoke and behaved like romans (public life) the women dressed, spoke and behaved celtic (private life).
When you speak of fly over, you must remember that at the time you needed lots of "pitstops", so even remote places would have some sort of standard... However i think other then merchants and armies, people didnt really move that much?
cheers
