How can we use a little psychology to get you to slow down when you’re driving? You’d be surprised. Very often road signs like “Slow” or a posted speed limit of, say 20 mph does not work. Drivers go past these signs and nothing bad happens so after a while they’re ignored. We try to make it more personal with signs say, “Drive as if your kids live here”, but often that doesn’t work. How about something trickier: what if we enlisted the help of those 3D sidewalk artists? What could they possibly do? You’ll find out.
