Right. I added oneway=yes or oneway=no for each way in Finland. About 
five were missing oneway=no and the rest were missing oneway=yes. (Even 
if oneway=yes is is redundant, it is good for quality control. The 
search for highway=motorway_link without oneway=* can be repeated, and 
only any new ways should surface; not the roughly 100 oneway=yes that I 

I won't change the processing of highway=motorway_link.

I just returned from a 175-km bicycle trip on a triplet with two kid 
stokers (OSM child labor). 30 km of that was on a major highway (trunk?) 
that is somewhat of a nightmare (no cycleways, heavy traffic, no 
shoulders) but the only choice in the area. I believe that the default 
style (correctly) does add bicycle=no to highway=trunk. When I get 
around to processing my saved tracks, I will add bicycle=yes, foot=yes 
to the highway, so that Garmin will accept it for non-motorized routing.  
For most of the trip (where roads existed on the map), I used car 
routing with shortest route.
