[OSM-talk] Lane turn restrictions

[Yann Coupin]

Plus what does "inner" mean on a oneway road? I think it's crucial  
that lane 1 is either left or right depending uppon what is decided  
but that it stays the same accross the world. It'll be unusable  
otherwise.

I propose 1 is left because we start to write from the left. It's  
completly arbitrary, but that way at least it follows a logic that  
stays the same accross the channel :) And since the tags are in latin  
characters, it's just to be consistent, not to ignore people writing  
in arabic or hebrew (if people still take offense, I did my best not  
to ;)
