Actually this is quite interesting sociologically. Your title says “The Art of using public transport”, but what these kids are doing is appropriating public space for private purposes. It’s fundamentally not so different from any conspicuous group activity in the public sphere: a gang of hoodies on the street corner, or a bunch of drinkers making a circle round their ‘territory’ in the pub.
Actually, I do have a pasting table remarkably similar to the one they unfold on the video. I’m blowed if I’d want to eat off it though.
And just what all this has to do with environmental solutions defeats me 🙂
These kids weren’t using the train as a means of getting from A to B, they were using the price of their tickets to rent performance space.
Although the video kicks off at Kilburn station, the main event apparently takes place on the Circle line, judging by the yellow handholds. It looks as if the group gradually assembled around the Circle, stayed on for a complete circuit to stage their banquet, and then got off when their stop came round again. So, public transport as a means of getting from A to A.
