cycleway=shoulder doesn't seem right to me, either, and I'm a fairly 
frequent cyclist (or was, before kids). 

*If* we are going to mark shoulders, I think we need a series of tags, such 

shoulder:width=4 ft
shoulder:rumble_strips:yes/no/aashto         (this is very important for
                                              cyclists, as continuous
                                              strips render the shoulder
                                              useless for cycling, and yes,
                                              there is an AASHTO standard)

Has anyone run this by the OpenCycleMap folks? They're the only likely data 
consumer for this information at present.

Alternatively, maybe cycleway needs an "unmarked lane" setting for these 
situations, though that would imply the local authorities are intending for 
cyclists to use the shoulder, rather than just tolerating their presence 
(the usual situation).
