There may be some lack of uniformity across the dataset, but there could also be a lack of uniformity across the user expectation level as well. Some of the first pass OSM highways in Alberta were VERY crude. In comparison, GeoBase data looks really good. However, I have laid down some pretty detailed GPS tracks that make the GeoBase data look kind of crude. One case in point was a circular route in Ft. McMurray that described a roadway called Belgian Green. http://www.openstreetmap.org/browse/way/25518315 I used 21 nodes to describe it from a GPS track. I think GeoBase used about 10 or so. Even my 21 node track is pretty crude. GeoBase also like to show intersecting dual carriageways as all intersecting at a single point. (Can't find one right now...) It's really a preference more than a "be all end all" thing, but I think that we as an OSM community using just consumer grade equipment have the ability to enhance the detail shown in the GeoBase data that I have seen so far.
