Actually I think you might tag that kind of streets with two highways. 
One with oneway=yes and lanes=1 and the other one with oneway=yes and 
lanes=2.
There is a German Wiki page considering defaults, but a small comparison 
with real streets showed those defaults arent any good.

Think its strange somehow because it really is something you just cannot 
not see if you are tagging a street ...
