Hi Jonas,
I have checked your test case. The way 4400960 is still on the right
side of the motorway even after cutting. But the distance is very small
and there might be some rounding problems of the GPS device.
mkgmap calculates the angle between the link and the motorway before and
after cutting. Before cutting the angle is 3.55° and after cutting it is
0.28°. Maybe the 0.28° is too small and mgkmap need to correct it. I'll
put it on my TODO list.

Hi Jonas,
thanks for the test case.
I will have a look on it but it will take some time.

Oh, I forgot the link to the minimal test map and .osm extract:

Hi!
I have an issue where a motorway_link which is modified by
--process-exits gives the wrong turn heading instruction in my GPS
(Nüvi 205). "Turn left at Exit 113" instead of "Turn right at Exit
113".
The way is http://www.openstreetmap.org/way/4400960
When looking at the map in QLandkarte it looks like the first two
ways created when the _link way is split are almost parallel to the
motorway. My guess is that it's somehow related to the relatively
long distance between the first and second node in the original
_link way.
I build my maps with the following (relevant?) arguments:
--adjust-turn-headings --route --housenumbers --process-destination
--process-exits
This issue can also be seen in the maps downloaded from
http://garmin.openstreetmap.nl/
