I don't recall exactly how I ended up reading this article about the craziest and smartest roundabout I have ever heard of. I mean, seriously, who reads, or writes, articles about roundabouts?
If you don't have much time, here's the short video explaining what it is about in one and a half minutes.
If you do have a bit of time though, I seriously advise watching this second video of a much more exhaustive demonstration of why this roundabout makes sense. I promise, you'll learn a lot about roundabouts and you'll never look at them in the same way.
