Hope you can help... because there's a great number of one-way streets in my city, which may be used by bike in opposite direction.
At this time, I believe the only way you can achieve what you want is to create a map specifically for bicycle navigation that ignores the oneway=yes if the cycleway=opposite* tag(s) are set. This would involve writing some rules for the style file. I am sure that the style file gurus on the mailing list will suggest something appropriate.
What would it take to duplicate the way in mkgmap, as highway=cycleway, oneway=-1? This could of course be done relatively easily by preprocessing the OSM data before feeding it to mkgmap, but I would consider it an ugly workaround.
Of course, such a map would not be useful for routing vehicles.
Nitpicking: I thought that bicycles are human powered vehicles. :-) BTW, are there any non-OSM Garmin maps that feature routeable cycleways? Such a map could be useful for reverse engineering. (I have only used OSM on my Edge 705, and I read that a commercial map of Finland lacks routing data for cycleways, even though some ways are visible on the screen.) Marko
