[OSM-talk] [Talk-us] MapRoulette update

I think we need to get lanes and turn lanes nailed down a bit first...then
there's the whole bit about how you're going to detect changes in lane
counts along the way, since this almost certainly would require splitting
ways to get counts accurate (and a big reason why I abandoned trying to
nail it down while working on alignment and relations in the Oklahoma State
Highway system, after it took me nearly a year to complete the OK 3 mess,
the other being that lane counts on two-direction ways gets messy in odd
numbers (which side does it belong to?) and how restricted lanes get
counted...the whole lane schema just isn't very well developed yet, and
that's going to need to come to fruition before we start shooting newbies
at tagging that en masse.
