I think the case can appear very often. Imagine a router based on OSM
data and you take the wrong roundabout exit. The router will re-route
you and most probably with a u-turn, back to the roundabout (but you
are right, because of the delays and distance, most probably after the
divider intersection node). But anyway, representing the "no-crossing"
is important for routing and we should consolidate the wiki between
the "overtaking" and "divider" tags.
Could we consider that "overtaking=no" applies to the end nodes as
well, like we do for the oneway restriction ?
