But if there are markings, I'd say it was a parking lot. Depends on context, though. If it's a little paint on the kerb, parking lane. If it's a road marking, parking lot. That's my rule of thumb, not a solid rule I'd apply in all cases. > > BTW, this is what NYC apparently considers a "parking lane": > https://www.youtube.com/watch?v=RJv4oleZAhQ > That's a "floating parking lane," according to the video. Looks to me like a parking lot adjoining a road at one side and adjoining a cycle lane at the other. I say this because of what is visible at the left of that "floating parking lane" - an obstacle. Even with no vehicles parked there, through traffic would be obstructed. Difficult to be sure, from the video, though. I'm glad I don't have anything like that around here, otherwise I'd have to figure out how to map it. > > Based on this discussion, it seems to me that that is *not* a "parking > lane" as OSM uses it. > That's not a parking lane how I'd use it.

I'm talking about parking spaces not rendering ever, as far as I could tell. Looks like carto implemented it when I wasn't looking. -- Paul
