Nice straw man you've made there. I didn't say that either of those 
forms of tagging imply the other. What I said was that both forms 
indicate that cyclists can ride in both directions and asked why should 
mappers be advised to use the more rare, less likely to be consumed, 
version when they both mean the same thing?

Here is a crazy idea: how about oneway:bicycle=-1? Nice and simple, 
saves you from having to add tags that indicate bicycles can't travel in 
the forward direction, and may actually be noticed by data consumers who 
are likely to be also be looking for oneway:bicycle=no.

Nope. I mean cycleway=shared as defined on the wiki page (from late 2011 
onward, so I didn't think it was such a new and radical idea). In 
Australia the only difference between cycleway=shared and 
cycleway=shared_lane can be one of these signs:


maybe every 5 to 10 km. I feel so much safer now...
