Show cycleway:left|right=opposite_lane

[pch14@…]

Streets where it is permitted to ride bicycles against one-way limits for cars often have lanes marked on the ground or even tracks separated by a kerb.

A simple cycleway=opposite_lane is not enough to know, which side this is on. CyclOSM works around, by showing lanes/tracks on both sides of the street. That is wrong though.

To the rescue, cycleway:left=opposite_lane (seems to be hardcoded in JOSM for the tag not specific to side) or cycleway:right=opposite_lane - mostly depending on country wide rules (left/right-traffic).

Please display the side-specific versions. Taginfo shows, they are just as common as the unspecific version.

Closed as duplicate of #20468.
A late explanation in the other issue makes this one moot. Closing as duplicate, because wontfix cannot be set by me and invalid is also not right.

Rationale: cycleway:left|right=opposite_lane|track|shared_lane|… would be a single tag for oneway:bicycle=no + cycleway:left|right=lane|track|shared_lane|… The availability of the two tags solution to the problem and its wide support by routers, editors and other consumers outweighs the shorthand notation by far. I do not see a reason for supporting this in my favourite editor any more. I'd even go so far as to ignore cycleway=opposite_* just the same, but that is another issue.
