travel - Universal Studios: Nobody walks in LA

Today at the end of the afternoon a few hours to hang out the tourist. Of course I went first to see the Universal Studio's in Hollywood. Obvious a very succesful destination, but it could intrigue me only for about an hour. "Nobody walks in LA", quoted an LA friend from a famous song. I defied that saying, even worse: I took the metro to get there and was one of very few.
LA is - compared to SF - a real city with between seven and eleven million inhabitants: just as in Shanghai nobody has a real clue. While Shanghai is only starting to build up a car park, in LA that is already done: the city has for that reason spread out over an enormous surface. It would take an expansion to Ningbo, Hangzhou and Nanjing to achieve a similar situation in the Yangtze delta. And many more, much wider roads. That seems now an undoable situation, even unwanted when you would ask me.
