The argument is that it's safer to stand side by side. But people probably walk for speed, not safety. So unless they make it a rule and enforce it, I don't see people changing habits.

that's not the argument at all- it's not safety, but total throughput. The speed argument makes only a bit of sense- a few people attain higher speed, but at dramatically lower total overall throughput.

"It’s more efficient if everyone stands on an escalator instead of some people walking on it,"

surely it would be even more efficient if everybody walked on escalators

dekhn
no because walking takes up more space per person, dropping throughput.
