Okay, so http://www.yargerengineering.com/articles/images/Traffic-Circle-Woodruff-Place-Indy400.jpg
is junction=roundabout?

And the only difference between a roundabout and
http://g.co/maps/nvhfh is that you can (supposedly) make a left at the
latter without going all the way around in a counter-clockwise
direction?  (In other words, if there was a sign indicating that you
had to drive to the right of the island, it would be a roundabout?)

I wouldn't mind.  There's something fundamentally different between a
typical New Jersey traffic circle
(http://en.wikipedia.org/wiki/File:Marlton_circle.jpg) and an island
in the middle of an intersection which people drive around in a
counter-clockwise direction

I certainly would give different driving directions in each instance
(something like "merge onto the Marlton Circle and make a right at the
third exit" vs. "make a left at the roundabout intersection").

I can't think of any true roundabouts
(http://en.wikipedia.org/wiki/File:NonUK_Roundabout_8_Cars.gif) in New
Jersey.  But then, I haven't lived there in over a decade.
