As well as Africa, how about looking at Hong Kong/Macau/China as an example of a busy land border which switches sides, including this work of civil engineering art:

How can we make a map for regular travellers between e.g. Shenzen and Hong Kong?

Hi Colin,

How can we make the behaviour deterministic where the map area covers both? For example, you can't make a rectangular box around the UK without including bits of France. If the splitter/mkgmap combo decides to start in the bottom right, the whole of the UK will be driving on the right. So I don't see when the "detect" option is realistically going to be useful. Between the UK and France there is a big bit of water, but there are many land borders between dor and dol countries. Can we get a combined map that contains both?

Yes, would be interesting to know how Garmin solves this problem
e.g. in Africa. I don't know how many roundabouts they have which
are likely to fall into a mixed area.
I think Steve said that it is possible to use boundary nodes which are
not all on a straight line, so it would be possible to cut a administrative 
boundaries.
