[Tagging] Subjective Tags was: designated bike lane

I think that adding a hazard=xyz tag is a good suggestion.  A bike-route renderer could then allow someone considering a ride to decide which hazards they were willing to accept, and which to avoid, and adjust the suggested route accordingly.

The main problem with subjective data was that people wanted to use the 
existing tags designed to describe the legality to describe "difficulty" 
(ability) of a way.

As long as different tags are used (as you describe) I see no problem 
with providing warnings
