A buddy of mine was extremely difficult to break from the habit of smashing the driver's side mirrors off of cars that dared to cut him off or share his lane while driving through Shanghai. That being said, I've parked my bike in front of a few cabbies and gotten off to discuss the finer points of safe driving. As far as driving down the highways around Shanghai on a motorcycle I'd have to say "Madness!!" Those drivers are absolutely crazy. Another friend of mine who was a stock car racer routinely flies down the roads in his Buick with me between Jiangsu and Shanghai and there is no way I'd want to compete with him and the other nutbars with my motorcycle. There's only so much you can do at 120 kph.
