Saw this really funky thing at a small crossing near my house. You press a button and the signal for pedestrians turns green. Now how cool is this! But I am already thinking about the unbelievable misuse it might lead to as well. Also, the chaos if it is fixed at busy intersections – there will always be people wanting to cross the road and therefore, pressing the button and stopping the traffic. I am really curious how this can work efficiently and effectively.
