Hot! How Traffic Lights Should Work


The picture comes from this Quora thread on “the best new products that people don’t know about.” We are in the 21st century and this is how I expected traffic lights to work by now. In this example, the light would require drivers to look at the traffic light for slightly longer to assess how much sand is left in the hourglass, and how fast it’s running out. The result might be more distraction rather than more usable information. Wouldn’t it be easier to just have a countdown, with the numbers rendered in green, yellow or red?
