Hi there,

Regarding this way (https://www.openstreetmap.org/way/402499411/history/8) you just switch from track to unclassified. In the spanish community we're discussing about what criteria do you use (in general, english-speakers) to consider one or another, according to the present imagery. 

The wiki definitions don't clear that up to us, at all, indeed. Could you bring us some light here, please?

Keep in mind, most of these elements are unpaved, and private cars shouldn't be routed through them (unless you wanna go on purpose, of course, to some specific place).

Thanks
BR
