There are several magic roundabouts - I grew up near High Wycombe which has one. https://en.wikipedia.org/wiki/Roundabout#Magic_roundabout

The Swindon one is notable because it was the first, and because it has the tightest geometry, which makes it harder to see how it works.

Hemel Hempstead, North of London, has an even better one.

It's actually 6 roundabouts forming a seventh (the Swindon one is only five forming a sixth) and it's also over a waterway.

As the taxi drove us through that madness, my boss turned to me and said "okay, you were right, it's best we didn't rent a car and try to drive to ourselves".

Do most people just simply ignore the outer roundabouts? Otherwise I don't know how to explain this picture: https://www.wired.com/wp-content/uploads/2016/08/wired_see-h...

There's a group of cars on the very right simply driving through the roundabout instead of around the center dot; and the two red cars on the left side of the image also couldn't have ended up where they are without ignoring the roundabout right behind them.

"Only one fatal crash in five years." (mentioned in video)

That's hardly a good fact to support the claim that roundabouts are safer that well-regulated conventional intersections... which they are actually, and more efficient in terms of the traffic flow. But the "1 fatality in 5 years" is an useless data point that proves absolutely nothing.

Someone please correct me if I'm wrong, but that photo appears to be from some sort of staged shoot, which probably explains why it's not being used as you'd expect.

Edit: Here's another photo that appears to be from the same event http://matrixdaily.com/wp-content/uploads/2016/07/MTX_MAGIC_...

And a photo of the roundabout in a more typical setting: http://www.boostinspiration.com/wp-content/uploads/2011/06/S...
