True for overtaking. But it' correct for turning left/right and u-turn

Hmm, look at the wiki first:

and consider this assumption:
"By default, when a divided way has a junction with a non-divided way,
the division is unbroken."

But I agree that such assumptions are very hard to keep in OSM (where
usually a tag shall be self-explanatory).
