What if there is forest inside a large maxspeed=100 roundabout and a
lake inside the forest? :-) In my opinion, the right solution would be
never to share a line for highways and areas. The shared lines are a
nuisance when you add footways, cycleways, bus stops and the like.
On a somewhat related note, I noticed that some have started tagging
overlapping lines for landuse multipolygons: one tagless line for the
role=inner and another line (with tags) for the inner area. That is kind
logical, but overlapping lines can be confusing when editing the map.
