+1. Some days ago, I came across a mkgmap warning for a dead-end oneway
in a residential area that was riddled with landuse polygons that shared
points with ways. It was very hard to see that the oneway was not connected
to the road it was supposed to. I spent several minutes detaching the
landuses from the roads in the area.
