I really like this video, and I think it’s a reasonably accurate reflection of how efficient the Hong Kong Mass Transit Railway (MTR) can be. Essentially it’s someone trying to see if they can get from one station to another faster on foot than via the MTR. In short, they don’t beat the MTR, but even then only by the sink of their teeth.
There’s a UK version of it for the tube, which has the result going the other way.
Obviously both are a bit contrived, but still a fun experiment, not that I’d want to do the running myself anytime soon.
