As I keep advocating, we should be able to map lanes, but it makes no
sense to try and use ways to do this because as Ross keeps pointing
out it just looks messy.

If we had lanes our GPS routing software could tell us which lane we
need to be in to turn, unlike most states in Australia when turning
right in Melbourne you line up in the far left lane instead of the
centre lane, or was that way when I was down that way last, I doubt
things have changed since.
