I know zero about Shanghai but the first time in visited in August 2008, my friend that lived there said if I had visited just 2 months earlier it would have been a totally different experience because I'd have heard incessant car honking. He claimed the government banned honking your horn except in an emergency and then actually enforced it so that everyone got the message quick. Honk, get a fine. I was impressed since I didn't hear any honking. I can't imagine that being enforced pretty much anywhere else in the world.
