Thanks for that Jeffrey. I agree entirely that rendering should follow tagging and not lead tagging, my main concern at the moment is that UK rendering (blue for motorway and orange for secondary) is encouraging inappropriate tagging. I think we agree that one should clarify first how to tag what

If we can agree on the rendering rules and get both Mapnik and osmarender sorted out for the USA sorted out - they both work fine. Even if we had a production-ready mechanism for country-specific rendering, it would still be a matter of opinion, or more accurately, a matter of cartographic
