Interesting story about throughput experiments on the tube escalators; unsurprisingly, once you think it through, it turns out that keeping half the width of each flight clear for people to run rather than stand loses way more bandwidth overall than it saves for individuals in a hurry.
Trouble is, eny fule kno that you're supposed to stand on the right and that hurrying people can scoot down the left, and no one likes change, least of all British people... so getting them to do it differently withoutchanging the design and rationale of escalators themselves is, unsurprisingly, a lot of hard work. But it's an interesting case, because the practice in question has been and is indeed still being shaped and encouraged by signage all through the rest of the underground system -- signage that's at least as old as I am, I'd guess, if not older. So we're seeing here not the challenge of developing a new protocol or ettiquette for a new technology, but the challenge of erasing a deliberately introduced and well-established individualist public practice and replacing it with a more egalitarian one, without recourse to major material intervention in the infrastructure underpinning said practice. If TfL can crack that problem, it'll be quite an achievement.
