Umm... you shouldn't do this. The rule in OSM is that if you cannot
physically drive between the lanes, you should use 2 OSM ways. if you
can physically do it, then use one OSM way (even if that would be illegal).

it (in IE/UK an unbroken white line in the middle), which are mapped as
one single OSM way.
You should maintain the OSM convention of single way implies they
"physicallity" of driving across, and says nothing about the legality of
