There has to be at least a physical barrier or kerb/grass island before we can map road junctions as separate ways.
I am sorry, but I did not make this guidance up. If you are worried about how to map the layout of such road junctions, we can use one or more of the following tags:
Any mappers who still split road junctions divided only by hatched lines should transition to the aforementioned new scheme.
In addition, I am minded to consult on whether we should have a
hatched=yes tag or something similar to describe such layouts.
I do not think
dual_carriageway=no justifies the use of separate ways for road junctions divided only by hatched lines.
