Ah yes. I changed it because it is not a road for cars, and the area is decimated by 4x4s, who see it as a challenge to there. Local community (me included) are outragfed that this is happening, and I wanted to demonstrate that some careful tagging could help them, and that OpenStreetMap participation was good for them. Obvs, I was not careful enough! "foot"="yes" does just the job.
I'd have to check if it is actually a 'private' road (local families/farmers), but is there something else I could do to deter motorvehicles in this beauty spot? There are terrible mages showing the complete destruction of natural environment here.

Best,
