At least in the US, such map data is public information, yet trail maps
still rarely include motorways (or if they do, just as a generic,
classless road along with any other ribbons of pavement).  I hazard to
guess it's likely a feature that's downplayed or removed due to a lack
of relevancy relative to the data the map is trying to convey.
