You're right. Last holidays, I went to beautiful place in Spain. A way covered in Ferns was marked as an OSM path. I guess it was, but did not get cut this year or the later. So we tried and failed 30 m after.

It's important to keep some mysteries despite precise maps.

That's why I'm at the same time fascinated by 3D "splats", but also worried to be spoiled.

They're great for places we already know (inspect your roof's shape for instance), but they spoil discovery.
