<p>Hi again,<br>
</p>
<p>lets ignore the cycleway:left:oneway=-1 for a moment and just
consider cycleway:left=lane vs cycleway:left=opposite_lane.</p>
<p>To me the main difference is, that cycleway:left=opposite_lane
can only be used when the carriageway itself is a one way street
(legally speaking).</p>
<p>because of that, opposite_lane is conditioned on and mixing two
conceptional different physical objects (cycleway and
carriageway), that are only represented as one osm way.</p>
<p>Remove oneway=yes (<font size="-2"><i>form the carriageway</i></font>)
and you need to change cycleway:left=opposite_lane into
cycleway:left=lane, too.</p>
<p>Also, have you considered, how you would tag a dual-cycleway on
the left-hand side of a one way carriageway?(eg cycleway:left=? +
cycleway:left:oneway=no)</p>
<p><br>
