The lanes tag is very simple, it is just a count.  But I think the  
point is that we could use more information than just a count of  
lanes.  For example, if a way is not one-way, and the lane count is  
odd, which direction has the extra lane?  It just doesn't say.

See, for example, the lane information proposal in:
