You know the person, the one who looks up an escalator and sees everyone standing on the one side but chooses to stand on the opposite side. The side to stand varies from country to country.

There’s a solution to this problem. A sensor in the step detects when you’ve been stationary for too long on the wrong side and a little cattle prod comes out and zaps you. Maybe a disembodied voice which says “move” if the budget stretches to it.
