This year the event is held in Shanghai and showcases the latest in green cars.
Looking at some of the Chinese number plates, I would hate to get caught up in an accident. "What was the registration of the offending vehicle?" says the policeman.
"Errr. Squiggle, squiggle, something that looked like a Christmas tree and squiggle."
I don't see any photos of people walking, as I did today. One mile to and from the shops sporting a t-shirt at 0C (32F). Bracing but green!
