As much as I hate Shanghai traffic, it seems to work. If this number of people were driving in a city like Toronto or Vancouver we would have complete gridlock. I cannot help but wonder if more strict enforcement of traffic laws in Shanghai would not hinder rather than help the situation. That being said, I completely detest the Shanghai left turn. There is nothing more scary than coming around a right hand corner & encountering someone driving straight at you in your lane trying to beat oncoming traffic.
