What seems a strange and complicated ritual is actually simple: Swindonians enter the magic roundabout from one of five points. They aim their car at their destination, yielding to those ahead of them and following the white markings in the pavement.

While a driver entering a normal roundabout might have to make an entire turn to arrive at their destination, a person of Swindon in a magic roundabout can cut through the circles more quickly. A complex pattern emerges.

Roundabouts or traffic circles are fairly uncommon here in North American and can be very confusing to those unfamiliar with their operation. I generally have no problem with them but this “circus” looks like madness. I’m never going to Swindon.
