Also in London I genuinely felt as if Big Brother was watching me all the time. Cameras all around and someone is constantly telling you something over the speakers. I don't have that chilling feeling in Germany.
By the way, cudos to your rail transport - from what I saw it was quick, clean and easy to navigate. Also not horribly full even at 17:00 on a Monday. Your busses are a bit more shite, but we'll let it slide seeing as I got to ride on the front of the second level of a double decker. It was glorious!
People were also surprisingly nice in showing us the way even in the hustle and bustle of London.
