The countdown walk/don’t walk sign:
No one talks about this amazing addition to urban living. And it’s not just super for the pedestrian in us but also the driver in us. It is literally changing my driving habits. I drive much more smoothly now. I can anticipate accurately a half or more block away whether I can make the light or not. While sometimes I will speed up, just as often or more I will slow down. Even when I speed up I know just how much to speed up without over accelerating.
