Thanks so much for posting this. I was wondering why since the redesign my movement at Kings Cross was taking so much longer than the route my parents would take with me as a kid going to London for day trips to the Science Museum or zoo.

If I lived in London I'd like to think I would make a project out of finding all the shortcuts and hacks like this applicable to my routine. I'm sure the video is only the tip of the iceberg (especially as Tom Scott generally really knows how to make his stuff short and sweet - anyone else feel the video was edited to pretty much perfection?).
