The Magic Roundabout in Swindon, England
This is old news, in fact over forty years but still has the power to intrigue and wow the newcomer. A seven – circle roundabout in Swindon, South England works with traffic moving anti-clockwise on the large external circle but clockwise on the inner ones. It is guaranteed to confuse the sat-nav let alone the new visitor. Even though it appears complicated and scary, traffic is slow moving and few accidents occur. The only rules are to follow the lines, give way to vehicles already in the roundabout and then be on your way. Simple.
Thus U-tube clip is a bit car sickly but will give you an idea.
