I circumspectly circumnavigated this monstrosity which needs circumscribing, when I was last in the UK.
Ok, I am used to roundabouts - after all Canberra is the renowned capital of roundabouts in Australia. Try a 2-km circumference! One near me merges major roads into an interstate highway. Unfortunately it is not round, more oblong. About once a year a truck coming from the side would find the curve tightening, and fall over. So now there are 18 sets of traffic lights, on the one roundabout.
Anyone got a copy of the torture track that Plessey had as its logo?
