I thing the "lanes" tag is best not used, unless there's more than two marked lanes on a two-way road, or more than one lane on a one-way road. This is the recommendation in the Australian tagging guidelines: http://wiki.openstreetmap.org/wiki/Australian_Roads_Tagging#Number_of_lanes I have two reasons for arguing this. Firstly, it's something else that would need checking when doing OSM maintenance (and quite unnecessarily). And it's something else to get wrong if it's used routinely. It's easier for everybody if its used is reserved for the special cases. Secondly, as an active mapper, I often download the whole of Australia every week for use as route-proving on my Garmin GPSs. If every road in Australia had a lanes tag, that'd be a lot more data to download.
Similarly, even on the east coast, its not unusual to see dirt roads defined as 'tertiary' or even 'secondary'.
I think a lot of roads get "pumped up" to be more important than they are. The great majority of country roads should be "unclassified". It's hard to make a judgement as to when a different tag should apply. Is it a main connecting road between towns with a Post Office? How many cars per hour travel it? Another example is the tagging of the Hume Highway as a motorway. Most of it isn't. The Hume Freeway in Victoria is, but most of the NSW section has normal side-road junctions, and is certainly not a motorway. By tagging it as a motorway, we've destroyed this useful distinction.
