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?

Hi Gerd,

I am not sure if you understand what check-roundabouts is doing. It determines whether a roundabout is clockwise or not and changes the order if it doesn't match.

I haven't thought about correcting roundabouts. So maybe better leave it as option to rebuild wrong roundabouts but use some other option to detect of driving side?

For example:
drive-on=detect (count "dol/dor")
drive-on=left (the same as drive-on-left)
drive-on=detect,left ("left" as fallback, when "detect" fails)
