I agree with this.  There seems to be this ability to say that this is
wrong, but without constructive critisism that produces a viable
alternative, I'm at a loss on how to handle it any other way.

That's kind of where I'm at.  In the example changeset I gave in the
head of the thread, what replaced the individual ways was hov=lane
(the closest hov= tag would be designated, given that it's an access
tag), which obviously doesn't work because we don't have access=lane,
not to mention any individual tag misses the routing nuance.  So, that
completely misses all birds with any number of stones...

It's not ideal, surely, but given that we already have routable ways
sharing the same pavement area using multiple ways when routing isn't
straightforward or intuitive outside of these lines (ex: LAX's tarmac,
given runways, taxiways and the passenger apron all share the same
giant concrete slab; parking_aisles in parking lots), I was rather
surprised that the Ronald Reagan Freeway got crushed like it did.

Lacking a viable alternative that routes properly, I plan on going
back to my initial intuition sometime within the week assuming a
better way doesn't come along between now and then.
