I find it strange that we are still discussion whether roads that are
only legally divided should/could be split into 2 parallel ways, a
solution that we did - since ever - reserve for physically divided
The answer to your situation above could be the divider-tag, applied
on a single way, where it would solve many of these situations. For
more complex situations (several parallel lanes, some of them divided
legally, others not) we still would to have something at lane-level,
as the simple divider approach does not tell you in these cases, where
the divisions apply.
The interruption of the continuous line on ~points (=very short ways
not much longer than the width of a lane) could be modeled at
node-level (to avoid excessive way splitting) and for longer pieces it
would be on the way (which would then have to be split).
