I still do not get one major point which was totally left out on the first
scheme. What actually belongs to a "point" and how are they tagged. Especially
on big crossings and roundabouts I always was confused (e.g. it might be
possible that a part of this point is blocked but how do I know which one and
you might be able to use  the first/last exit/entrance of a junction but not the
rest. )

There was only the inspector and a overlay for the first round in Germany and it
worked.

Think this was all handwork.
