[OSM-talk] How to use lanes= for two way single track roads?

The "lanes" tag was in my original Map Features draft way back when and was
intended to map the number of physical travel lanes that the way represents.
That's certainly the usage I've always put it to. So, as you say, a two way
single lane highway is lanes=1

Cheers

Andy
