I was just thinking about motorways where cycling is restricted to the
shoulder a few days ago, and came up with cycleway=shoulder as a
possible solution.  Yeah, I think cycleway=shoulder is a good
solution, especially in cases where bicycles are not permitted on the
roadway itself.

The only hesitation I have is whether or not we might want to use
something more generic, so we can indicate when shoulders useful for
pedestrian access are available as well.

I don't like that one.  Traffic should be a separate tag.  Along with
speed limit and number of lanes, that should be enough info for the
routers/renderers to make a reasonable decision (preferably with the
input of the end user).  The problem with the subjective
cycleway=no_shoulder is simply that "relatively safe" differs from
person to person, and even from trip to trip.

Yeah, more tags for shoulders would be great.  The only problem is
they probably won't be heavily mapped.  Whereas the cycleway=shoulder
tag might get a bit more use.
