[OSM-talk] zones for motorway/in town/outof town?

[Greg Troxel]

I find this talk of overlapping polygons a bit boggling.  Things seem
far simpler:

  roads with an explicit speed tag use that tag.  This represents the
  situation where the road has a sign and that's been entered.

  roads in a "city center" polygon that don't have a tag inherit from
  the polygon (in the routing program, or mkgmap).

So as long as exception roads have speed tags, what's the problem?
