I just noticed that the Mapquest rendering of Dublin is a bit unrecognizable with Grafton St. and Henry St. given the same weight as paths through Stephen’s Green:
Should major pedestrian streets be defined as areas?
OpenStreetMap itself does better:

So maybe it’s a problem for cartography in Mapquest?
