That's okay; that makes two of us ;-).

AFAIK there is nothing exactly like that in the US. People do park on
streets (note 5th, 4th and 3rd Avenues, as previously mentioned), and
there is sometimes signage regulating this.
Actually, this might answer one of my prior questions; is =marked
supposed to be used for stretches that alternate between parking allowed
and parking forbidden?
BTW, this is what NYC apparently considers a "parking lane":
Based on this discussion, it seems to me that that is *not* a "parking
lane" as OSM uses it.
That said, I think the US definition may be "a lane which is for
parking, rather than through traffic, and which may be intermittently
present" (e.g. the above video). However, I am much *less* convinced
that it is useful to model them that way, at least in the current state

Ah, yes, that would be an issue. Not sure what was with the not
rendering, unless you happened to look at it soon enough after I
uploaded the changes. There does seem to be a variable delay between the
database changing and the rendered tiles being regenerated.

Agreed; if the road was mapped also as an area, it would make sense.

Meh, I'm happy to omit the restrictions :-).
