[Talk-us] Trunk VS primary,

[Mike N]

   I think many of the trunk VS motorway VS primary conflicts come from 
2 points of view:  on the one hand, people like to zoom out and see a 
coherent network of interconnected roads.   On the other side, there is 
the group that prefers the road be classed according to its regional 
characteristics, and not necessarily in the same class for its entire 
designated span.

   In the end, this would suffer from the same connectivity issue: 
should the US highway remain a trunk as it reduces to 2 lanes and drops 
to 30mph passing through a tourist area?   Would that tend to draw GPS 
navigation routes from nearby faster, parallel streets?  Or would it 
look like an ugly gap in the trunk road if it switched to primary in 
that tourist area?

   As an aside, I sense that the tendency to upgrade results in all OSM 
streets being promoted by one level, resulting in a compression at the 
top end and less class distinction at those levels.   But because of the 
subjective issues I just let it happen rather than re-edit any such 
changes unless they are massively changing everything in a region.
