Butoanele placebo de la semafor: de ce nu funcționează

Many pedestrian buttons in cities are non-functional, yet they provide a psychological sense of control. This phenomenon, termed 'placebo buttons', can enhance feelings of well-being. In New York, only about 100 out of 1,000 pedestrian buttons are operational, as traffic congestion has rendered many obsolete. Other cities like Boston and Seattle face similar issues. In London, pressing the button activates accessibility features, but does not necessarily speed up the pedestrian signal. Overall, these buttons can promote awareness and safety, even if they don't serve their intended purpose.
