When editing a road, I get the error in JOSM:
Suspicious feature combination - Same value of cycleway:left and cycleway:right, use cycleway for this.
Tagging corresponds to the reality on the ground. I interpret the warning like you should tag
cycleway=lane + cycleway:left:lane=exclusive + cycleway:right:lane=advisory
But somehow it feels wrong. Is the warning irrelevant here or is the current tagging not nice?
Thanks and greetings from snowy Austria
