The magic roundabout in UK


Tom Scott has a neat series of things you might have never heard about. One of them is the magic roundabout from Swindon, England. That roundabout is a series of small roundabouts at the edge of a bigger roundabout and it all works well.

If every driver pays attention to the regular traffic rules, then we won’t have any issues in using that huge roundabout. Interesting find: bird fly in the same way. They don’t need to know where the entire flock it. They only follow their own path according to its neighbors and the rest is already solved.
