Thanks. It wasn't my idea. I literally tested the spec "whenever you zoom in enough that there's enough room on a visible street to put a label, then put the label!"

I guess the person meant "on one spot" but since labels are frequently repeated I didn't see the harm of trying it out in the "worst" way possible. Still looks fantastic.

Maybe it was misspecified but I did what it says and I think it's great. A light grey might help but then again it could be easier to ignore black you don't need than make out light grey you do.
