My new intersection 8-(

Wow. We have roundabouts, too. Why do governments even want them? Is it supposed to look pretty? And the Lord's prayer won't hurt! :-)

Even if I were a fan of double roundabouts (I'm definitely not), this particular one is unique, with rules that only apply there, making it that much more dangerous. I call it a redneck roundabout because it's used by lots of pickup drivers who treat it like a monster truck rally.

And the US term is "traffic circle", except in Massachussetts, where it's a "rotary".  But the USA has had the bizzarre idea that traffic entering should have the right-of-way, which results in heavy traffic locking up the circle.  So we're starting to see yield sighns on entrances, and a circle so equipped is being called a roubdabout.

The Asbury Park traffic circle grew a set of strange appendages, which were enhanced in recent years by lane markings and barriers to ensure that everyone had to make their lane changes in the same restricted places.  40.225845,-74.037339 , if you want to have a look.

The elevated interchange on the elevated Bruckner Expressway grew out of a tint traffic circle, parts of which are still visible under the triple canopy concrete carriageways: 40.829362,-73.837872 .

We have free-for-alls in Calgary, but we call them freeways. :-)

Roundabouts can be useful at some intersections, but what I find annoying is when there are two or even three interconnected ones. Otherwise, I prefer roundabouts to give way signs

As someone who runs a horse farm, you probably have a truck. Just drive like they do here. Fearless truck drivers always have the right of way. Alberta is redneck country, minus the guns (only because they won't let us have them). We'd shoot each other at these roundabouts. :-)

Seriously, though:
Rule #1: There is no standard for exactly how double roundabouts work, at least not in Canada. Check local regulations.
Rule #2: If it's a double roundabout, be sure to wait for both lanes of traffic in the roundabout to clear before proceeding into either lane of the roundabout (e.g., cars going into the outer lane still have to wait for both lanes to clear since those in either lane of the roundabout may exit right in front of you). I almost caused a fender bender, not knowing that.
Rule #3: If he's bigger than you or his name is Bubba - yield!

I prefer an overseas roundabout I saw. It was either in Rome or Paris. A massive roundabout with no painted lanes that I could see. You simply drive around, following other vehicles in a questionable circle, and watch that you don't hit anything to your left or right. Needless to say cars yield to buses and big trucks there.

One wonders if the drivers on that circle mean to get somewhere, or if they're just sightseeing.

For fun, check out the long series of ramps and interchanges surrounding Newark Airport on three sides.  Start at the southeast, at Turnpike Interchange 13A and go counterclockwise around to the northeast, at Turnpike Interchange 14/A/B/C.  In that tangle of roughly 100 ramps, someone must have had the job of making sure that you can get from whichever Here to whatever There.  I'm not quite sure a human could do it.

To extend the fun, just north of 14/A/B/C is the Southern Mixing Bowl, a Turnpike self-interchange where three southbound carriageways and three northbound carriageways interchange into two pair of carriageways, one southbound and one northbound in each pair.  These are the Western and Eastern Spurs, which interchange with US 1&9 before going under Express 1&9, the Pulaski Skyway, which floats above the urbanscape like the spine of some fossilized steel dragon.  The two spurs then bend off on their separate routes, meeting again at the Northern Mixing Bowl before meeting Interstate 80.

The Skyway is worth a trip into GoogEarth.

Perhaps roundabouts are nature's way to ensure survival of the fittest. What else do we have to thin the herd? Be nice to those who might end up on top!

I like it. How much did that cost?

Texas!
