It's funny - no one has mentioned the 'countdown' features of the crosswalk/intersection lights.  You can see from quite a distance the interval of the light change.  People have clear warning when a light is going to go amber.  It's a scary "judgment" skill set when people rush the red at an intersection; the rate of recidivism is high with particular individuals.  I always say: if you don't self regulate, the government will do it for you.  And often - badly, I might add. So, here we are.  Don't like it?  Don't run the red!!
