[Talk-ca] Tagging sharrows (On-road markings for bicycle-automobile shared lane)

[john whelan]

In Ottawa we have paved shoulders which show up on the city's cycle maps as
recommended.  You can tag them but the normal rendering doesn't really show
them on a cycle map.  I set something up using Maperitive
https://docs.google.com/document/d/1WkJzx5NffRv0TIQgCFFGTQzyqbQ9XDphSLqcjuM8wGM/edit?hl=en_USbut
I agree there isn't really a consistant way that things are handled in
OSM for cycle paths etc.
