I think this reflects more on the poor self control of the drivers than the actual traffic. Petulant primadonna Californians (I say as a born and bred California) need to spend time in Atlanta and understand what real traffic is. I've lived in LA and currently live in SF. The worst traffic I've had in the US is in Atlanta
Oh yeah, the lack of air conditioning is just awesome. Brilliant. If I'm unlucky enough to get on one of those cars in bad heat, I'll never watch the show.
