I use my profile page to describe the reasoning behind my tagging, not to redefine the wiki.
In regards to highway=track and highway=unclassified, I have changed the wording on my profile page to exactly match the wording used on the Canadian Tagging Guideline page at https://wiki.openstreetmap.org/wiki/Canadian_tagging_guidelines
“The easiest way to remember this one is for a tractor, as it would have 2 ruts, where a tractor would be able to use it, or an ATV/Horseback/mountain bike/hiking would be able to use these roads.”
A piece of heavy equipment driving through an area with no prepared roadbed will leave two ruts. This describes a track, and there are indeed many instances of this type of road. Check out this spot on the map (using Bing as the background) to see an example of a Track next to a Minor Road. https://www.openstreetmap.org/edit?editor=potlatch2#map=18/48.98380/-55.37758
