maybe oneway-streets do more often have a cycleway only on one side of
the road, and they are mostly drawn in the direction of traffic flow
(although -1 is a valid alternative). Given that most of the ways in
the db are in countries with traffic on the right, but GB is strong
for mapping cycleways this could explain those numbers.

To investigate further you should also look on countryspecific
preferences to use tags vs. explicit geometry.
