Borders around that part of the world really are more of an implementation detail than anything important. I'm originally from Australia but living in the UK for a year or so. I went on a couple month long holiday around the UK and while I was in northern Italy, I decided it would be nice to spend a couple of days in southern Switzerland. I hopped on a local commuter train and like 40 minutes later I was in Switzerland. The next day I went on a bit of a day hike and 'accidentally' hiked back into Italy for a stunning view.
