Roundaturn 

A strange junction in the UK that has been royally messed with by the council to mimic a traditional roundabout but happens to just be a collection of turns and corners and isn't covered in any driving lessons before EST. 2010. Sometimes it can include traffic lights and giveway signs that don't make sense for a roundabout. Mostly found in citys that already have a bad rep for traffic but the council want to add extra obstacles that you have learn how to deal with, first timers have no hope and experienced roundaturners will piss all over other drivers whilst beeping their horns and shouting they are doing it wrong.

Looks like we have another victim of the roundaturn, I can they even drive!
