People who have never been to L.A. really have no idea how insanely huge it is. Driving to my apartment from the start of city (before you even get to L.A. county) and having the city just keep going and going and going for two hours and not because of traffic jams is something you have to experience to truly understand.
I was in Tokio last year and it’s really amazing. I have never seen such perfect efficiency and punctuality, and I’m German! A huge factor though is that all the people follow the rules and are mindful of everybody else. Nobody standing in the way, nobody pushing or shoving other people. Also, despite being a mindboggingly huge metropolis, there seem to be hardly any traffic jams. The world could learn a lot from Japan concerning transport.
There is no reason to push and shove and stand in front of the door to get in before letting people out if there is a train every 3 min. Seen the same in Singapore. You arrive at the station, see your train is already there but you dont care. You dont run you dont rush because it doesn’t matter. You just take the next one
