> "I don't class it as a 'lie' to quietly favour crowds flowing in a safe manner over the quickest route"
I do understand your main point but it's by no means the "quickest" route. Following the signs tends to spread people out. Even at busy times, it's still quicker to take the shorter route out, despite the extra crowding. Regular commuters already know this.
This is a good example of the conflict between individuals who want to get between points A and B as quickly as possible and the station that wants manageable flows without crowding.
