I think it's pretty obvious by this stage that OSM is more than just
for navigational uses. And I think it's too late to try to restrict it
back to just that.
So I think the ability to map roads as "directed areas" is worth
looking into - this seems to me to be the only problem raised so far
about the original poster's question, i.e. "mapping everything as
areas" (are there others?).
For directed areas, I actually quite like Teemu's idea of using an
ordered set of node-pairs. Any issues with that, or alternatives?
Re: Morten's suggestion of a "multiplex", is that just for
intersections? If not, could you explain how you would use a
"multiplex" to map a road or lane as a directed area?
