> https://www.openstreetmap.org/way/102969056 - a track in the forest. Even with the better Esri pictures there is no track to see!
> https://www.openstreetmap.org/way/370198123 - split the track, because sections are definitely different. For one part grade4 might be OK. For the other, grade5 at most.
> https://www.openstreetmap.org/way/134726358 - a big field. In the current aerial photos (Bing, Esri, Maxar) there is no track at all!

> Denmark:

> https://www.openstreetmap.org/way/290360323 - On parts of the pictures a track is partially recognizable, on others there is no/hardly any way. grade5 is no added value there
> https://www.openstreetmap.org/way/826303189 - A large meadow where the tractor has cleared a path. If then grade5 but not grade4

> Turkey:
> https://www.openstreetmap.org/way/203478714 - another track next door that looks like the same or bigger parts is grade3, this grade4. But they could all be grade2 as well...
> https://www.openstreetmap.org/way/294278418 - grade4. In my opinion rather grade2 or grade3. Position correction urgently needed. Well...

Mind that Modest7 used Bing imagery despite better imagery is available
in parts of Germany but not used by iD by default.
