You are right, since these streets are rare, there is no need to add the value "inverted".
With a tag that has been used on 4 countries and 14 highways, it's a bit > too early to analyse mappers' interest imo. > Actually, it's not early, this tag was documented since early 2012. But let's hope this lack of interest can change now. Ok, I have officially extended this tag's use on highways. Please review: http://wiki.openstreetmap.org/wiki/Key:driving_side One question: I am using the following template on this wiki page to show one example: <map lat="-26.30884" lon="-48.84413" z="17" w="350" h="100" format="jpeg" layer="mapnik"/> However I want to use Mapnik's zoom level 19. But the wiki won't let me have zoom levels bigger than 17. I believe this template was not updated to know Mapnik support bigger zoom levels. Does someone knows how to fix this?
