That's always the problem in OSM:
Is it meant as a "physical" tag or as an "intenionally" tag?

I would appreciate it, if we can reserve such general tags like "lanes" 
for general physical description and describe intentionally tags with 
their precise intention.

lanes=4   physically all lanes

So I second Anthony.
