at all in a router using it as a hint.
But maybe that's just because the places where I use OSM are mapped
wrong.
Using NE2's criteria, trunk is not really any different from a routing
standpoint than primary. Using mine, trunk is something that would be
primary if it weren't a physically better sort of road, so should be
preferred over a nearby primary if the distances are similar. I'm
harping on physical characteristics for this one particular tag because
I think without that as a differentiator, it's basically useless fluff
we shouldn't be using at all because primary already covers that usage.
