I have thought like this some time before, but this approach creates
lots of problems and therefore I changed my mind: Where do you put
fences, walls and other barriers that limit the landuse? On the
road=highway? This cannot work, of course you will try to put them on
their actual location: the landuse extents (in many cases) UP TO these
barriers (or buildings, ...), then there is usually the sidewalk (in
urban areas), then parked cars, grass-beds, and then finally the road.
If you map the landuse connected to the roads you complicate life of
everyone that comes after you and wants to add these details (like
barriers, highway-areas, ...).
