Roundabouts are something, along with BS1363 plugs, that the British bequeathed to their ex-empire, Africa especially. Gaborone in Botswana is plagued with them along with East Africa. I remember being driven in the hotel shuttle (a 10 seater minibus) from Nairobi airport to a downtown hotel at high speed and approaching a roundabout full of high speed traffic. The bus made no effort to slow down. I cannot tell you how we got on to the roundabout as I instinctively closed my eyes! I suppose if everyone is going the same speed (fast!) and no-one looses their nerve and slows down you just mesh like gear teeth [Linked Image]
