The tag oneway=yes on an osm way does not only mean "this is a _road_ with a oneway sign", but "traffic should not traverse this way in the backward direction". For the simplest example, most dual carriageway roads do not have a oneway traffic sign on either carriageway, they might not even have a "no entry" sign for the opposing direction carriageway (just a "pass this sign/obstacle on the right" at the intersections, if even that). Even the no entry (round red sign with a yellow/white horizontal rectangle) sign _effectively_ makes a short section oneway: every vehicle has length, so at some point coming from the "oneway" direction, there's at least a small (but several meters) distance where they aren't allowed to turn around - if they did, they would unavoidably pass the no entry sign. -- alv
