This is just one of many situations where a "forbidden turn left/right"
should apply, but we currently lack the proper way to tag that. So, as the
ways physically cross each other, I usually map this "crossing ways"
situation with nodes in all crossing segments, waiting for some kind of
advances relationships  to be implemented .
