Hi Baloo!
My name is Manju, and I’m a mapper on the OSM team at Lyft.
Thank you for your comment. As we discussed earlier https://www.openstreetmap.org/changeset/173982054#map=19/35.464086/-97.510757&layers=N, Our general approach is to add lanes and turn:lanes tags only when there are visible turn markings on the road or signs showing possible turns. In this changeset, I only saw a marking for a left turn, so I used left|none.
We have also started a forum discussion on this topic (https://community.openstreetmap.org/t/consensus-regarding-lane-and-turn-lane-tagging-guidelines/133364), where we outline our approach in more detail. We’d be glad to continue the discussion further there.
Thank you again for your comment and for your contribution to OSM!
Best regards,
Manju
