In an earlier post I'd made reference to idiots who step off of crowded escalators and just stop. Apparently I'm not alone in this observation: As part of a workshop at Geneva's recent Lift Conference, participants even brainstormed the above solution to keep escalator-stoppers moving.
It was called the Unpleasant Design Workshop and it was held by Gordan Savicic and Selena Savic, who run the amusing Unpleasant Design blog. While the workshop was intended to quickly brainstorm "a map of behaviours and social groups unpleasant design could discriminate against," their website does that and more, cataloging photographs of urban phenomena vis-à-vis design and highlighting fanciful design proposals intended to curb rude, idiotic or antisocial behavior.
