This issue needs to be fixed. I keep telling my wife someday soon there will be an accident and it happened so and sad to see, a fatal accident too. The simple way to fix would be just not allow free turn when the walk sign is on. It is just frigging crazy.  I know drivers have to be careful but frigging there is a green turn signal on too when the walk light is on, so, it is bound to happen to anyone. Yes, people are going to say how can I say that and it is the drivers mistake.  What I am saying is that it could have easily be avoided if light was red when the walk sign was on and a big No turn on Red blinking sign too.  Such a simple fix to this massive issue.
