Despite not liking having to do it, I would map it. WeeeZer14 and others have posted good reasons why it should be mapped.

At a normal 4-way roundabout, it'll say "at the roundabout take the 1st exit" for a right turn...then 2nd exit to go straight, 3rd exit to turn left, and 4th exit for a U-turn.

Maybe I'm missing what you mean by a "normal" 4-way roundabout... But a roundabout for roads meeting at right angles, it will never say exit number, but will say turn or continue for all but the u-turn, for which I imagine it will say 4th exit.

From what I can tell, no....

Not likely...

Only that one that's there in the image (in the last year or so...)

The road doesn't change names at the roundabout, the road changes names at the town border which is to the west of the roundabout. So we're still going to have the extra node "issue", but I don't think that is enough to warrant not mapping it...

Very good point...

WeeeZer14 wrote:3.) Someone is going to think there should be a roundabout there. Do you trust the average editor to do it right?

Someone already tired to (and did it incorrectly) after my original post...

As always, Alan does a good job so summarizing everything, I'll be mapping this shortly...

In CT, that's officially (CT DOT) not a roundabout, it's a "traffic calming device"... Doesn't keep people from not knowing how to navigate them (go around like a traffic circle)... Personally I think it's too small to try to map as a roundabout...

I have not been mapping roundabouts with less than three streets connected to them.

I believe it is angles and number of exits. My limited experience matches the explanation in the wiki, but its not like I measure the angles to be sure.
EDIT: Yeah, what Timbones said.
