According to the description, one-ways would be inferred from GPS tracks. This is error-prone.
Some time ago, Mapillary was proposing to tag this road with oneway=yes. This is wrong and can be seen as false using the aerial imagery (painted arrows on the narrow road shows that it is not a one-way) or the street imagery but just because you see a give-way sign from the adjacent road.
So please don’t tag as oneway=yes except if you have proves of that.
Likewise, transforming path into service is probably not correct, on countryside highway=track is probably a better option (usually you will find chemin d’exploitation/CE as reference for the track in the Cadastre - French land registry). IMHO, no automation is possible (except if you do those checks automatically) .
