To follow on from what Ralf said; as oneway=yes is implied, removing it will turn them all to two-way. There are far more one-ways than two.
The two-way links without the oneway=no are incorrectly tagged & should be amended.
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 added.) 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. Best regards, Marko
