Then it is up to the driver to follow the rules, and allow the router to re-plan.
Mapping to this level is really a non-starter, mapping every solid line is not going to happen. On rural trunk roads they are just frequent, ass they are used to prevent overtaking on bends, and there are a lot of those.

As I said earlier physical separation doesn't necessary mean "cannot
pass", because physical obstacles come in all kind of different shape
and form. Where I live there are plenty of cases of physical
separation that any ordinary SUV could easily cross. And then there's
the kind that would require a tank.
I think that it would be a more pressing objective to be able to
provide a legal route from A to B than to cater for all the shortcuts
that are possible but not legal. Of course the former doesn't exclude
the latter and one could conceive of new schemes to indicate where
it's possible to drive but not legal.
