In openstreetmap, tracks should get additional tags such as tracktype, surface, smoothness. If such tags are present and seem to be reliable, then OSM can be used to plan trips. Otherwise it is just too risky to rely on OSM. In particular in harsh climates and if there is no way to get help. I.e., before using OSM, assess the quality of the mapping done by the local community. Anyone can draw lines of a map by looking at satelite images. It doesn't mean that such lines are passable.
