Detection of unusable parts of tracks

I have a potentially useful and fairly large collection of tracks in Kenya, because I regularly drive and fly there and record all my movements. I would like to upload these tracks, but have one question first:

Does OSM detect and avoid unusable parts of these tracks, preferably automatically?

The unusable parts I can think of are:

• Flight tracks. They could be recognized by the persistently high speed, by the lack of any sharp turns, and by the fact that nobody else ever moves near or parallel to any considerable part of any such track.
• Game drive tracks. They are actually useful, but even after they have been used for many years, they can become disused and disappear over the course of a few years. The most useful ones could be recognized by having been used multiple times over the course of more than one year. However, OSM would need a mechanism to remove them after they have not been used at all in something like 5 recent years.
• Tracks into private property. I don't switch off the tracking when I enter a private ranch, for example. This cannot be recognized automatically. I guess though that the resulting mapping is OK, particularly when it is a dead-end road anyway. We do map roads in large private compounds, right?
• Off-road driving. I guess this should not be mapped. Such tracks can be recognized by not being used multiple times over the course of more than one year, so it is possible to detect and ignore them automatically.

A related question is the recognition of the quality of the road. The only method I can think of is to map classes of roads depending on speed. Since it is always possible to drive more slowly than possible and since the GPS may occasionally jump, I think the extremes should be ignored and the middle speed range should be used. The median is surely a better indicator than the average. Of course a road should never be mapped from just one track. The absolute minimum in my opinion is two similar tracks that are very close to each other and ideally at least several months apart.

But the general question remains: Does OSM have the means to do automatic track preprocessing of this kind at all? If not, perhaps it would be better if I did not upload my mixed tracks.

I know that Tracks4Africa has such software, but I cannot deal with them, because they do not communicate properly. I think though that automatic mapping from tracks is the only method to get useful maps for upcountry Africa and other developing countries, because there simply are not enough people there who have the time and the money to do manual mapping. I certainly will never find the time to turn my tracks through large areas of upcountry Kenya into a perfect map.

In some areas even GPS tracks will be scarce or nonexistent, so it is important to make the very best use of what is available. Please consider that even a mediocre map of a road, made from a few tracks, is infinitely better than not having that road in any map at all.
