you could have a relation to say that there is a linear possibility to
switch between the lanes (proposed area relation). This would make
some things much easier (we could use standard tags on the ways and it
would be clear without counting, which tag applies to where, the
geometric layout would be right before you in the editor, and you
could also model spatial details as fine as you like (up to single
holes in the pavement). On the other hand we would have much more
geometry for roads in the db.
