In my area, the walk/don't walk signals are crappy. They give you two seconds or they tell you to walk in a bad time, or tell you to stop walking halfway throough the street. I absolutely HATE it when I see parents teaching their children only to obey these signs. They should be teaching their children common sense. The "don't walk" signal is on for the duration of the time when it is safe to walk, it only flips to "walk" for a second right before that light turns green. What's worse is when the kids panic because the sign changed while they were mid-street. You have to use the old stop-look-listen on intersections with no traffic lights, so why not teach the kids to use the same common sense method when there are traffic lights?
