Please re-read my previous posts on this matter, regarding the road I live
on.  It is bi-directional, but it does not have two lanes.  Are you
suggesting we pretend it does?

We'll see.  I just took a look at the section of the OSM map related to the
example I gave earlier, and it's too much of a mess for me to fix right now
(it has a major highway listed as one way in the wrong direction).  But when
I fix it, I'm going to use separate ways, because that's the only way to get
the routing data to be correct.  If someone is going to revert me, I hope
they will invent a method to get the routing data correct first.

No, it's a redesign of the whole system.  A system which wasn't made for
per-lane routing information.
