Dear John, You underestimate the intelligence of OSM contributors and their motivation to make the map better. Particularly you underestimate their wish for better highway shields. You think increasingly specific network tags are too complicated for OSM contributors? Are you familiar with the great success of the Karlsruhe addressing Schema?[1] ;-) They will tag it. Absolutely they will tag it. When Mapnik support for local shields is adopted on osm.org and announced on talk-US it will take less than 7 days for the US Interstate system to have shiny new shields from coast to coast. I'll send you a bottle of Canadian Maple Syrup if I am wrong. > In the case of US interstate it should just be network=I, state > highways network=S "S" and "I" are so lacking context as to approach line-noise. "us_ny_ny_co" even hints at the right answer, without reading the docs. > That is enough information combined with a database or shape file with > all the meta information about what shield exists in which location, Those are mandatory with your incomplete tags.

I agree that failover to the UK style shield is better than nothing.
