If you were not trying to tag this situation, but explain it to your
non-OSM friends, would you say that there are 2 lanes in that picture
At least in Belgium a lane is defined by having some white markings on
the ground. If there are no markings, there is only 1 lane. I do not
know how it is defined in other countries. From what Thorsen wrote in
this thread, I think it's the same in Australia.
