I don't think Chris is suggesting that posted access restrictions should be
a sole criterion for tagging a highway as "motorway."

In Kansas, Signs indicating access restrictions are posted on the on-ramps
to interstates and some (but *not* all) non-interstate freeways. K-10, for
instance, has posted access restrictions on the Douglas County segment, but
not on the Johnson County segment. Both sections of K-10 in question,
however, are clearly freeway, and properly tagged as "motorway" in OSM.

Back to the question at hand (how to treat super-two facilities): While
KDOT *state* maps do not distinguish between 2-lane controlled access and
non-controlled access facilities (and, since 2010, the same applies to
non-interstate 4-lane facilities,) *county* level maps published after 2007
do show controlled-access facilities, regardless of the number of lanes.
Those county maps show US 169 between Chanute and Iola as a
controlled-access facility. Thus, it is properly tagged as motorway under
Chris's second suggestion ("If it has full access control, it's a motorway.
 If not, it's not one.")
