Cape Town Traffic Circles

I was in Cape Town recently, and besides the coked up vintage hippies with their pretentious glasses and oversized curtain-like dresses... people in Cape Town CANNOT drive. There seems to be no understanding that in the art of driving, especially when there is an oversupply of cars, it does not make sense to cut into lanes when its not your turn... you just hold up traffic. The sum of the whole is greater than its individual parts?

Besides this madness, they have these massive four lane traffic circles. Yes, I know, four lane traffic circles? Obviously this was the breeding ground for the genia (pronounced jeen-ee-i) that mapped out Pretoria. What I can only guess is an attempt to correct moronic Cape Townian driving, they have put in traffic lights IN the traffic circle. Huh? Isn't it reduntant to have both?
