I don't like it that much (don't like the cycleway:left/right tags
either, though). I'd prefer an integration into a generally usable lane
model with information about lane ordering. Then I could also map that
road with tree lines *between* pavement and car lanes properly.

I guess it's ok as a temporary solution ...

As with all left/right tags (as well as forward/backward, up/down,
oneway, incline, etc.), this would certainly refer on the way's
direction in the OSM database.
