Relations with `oneway=yes` are wrongly converting roads to one-way about organicmaps HOT 6 OPEN

ah ok, 1911 uses are on relations with type=route (and only 2 on 'type=restriction'). The fix would be to not apply surface/oneway etc tags from route relations.

Which is the semantic of tag oneway=yes on a relation element? It's not specified in the wiki https://wiki.openstreetmap.org/wiki/Key:oneway

Probably we shouldn't infer all tags from relations, but should apply whitelisted ones only.

Good catch. We don't take all tags, but the current logic is very complicated and aims to patch OSM mapping traits.

I will put a crutch, but I still don't have a clear vision of OSM mapping here.

1. For example, this https://www.openstreetmap.org/relation/12126834 I suspect that oneway=yes should be taken from this kind of relation (route=ferry). I see a contradiction here with route=road.
2. Should we take "surface" from route=road relations?

Nope, here is a "backward" route that uses the same way: https://www.openstreetmap.org/relation/12234840

I think its mistagging.
