I'm not sure what's unsafe about a traffic signal with a sign next to it reading LEFT TURN SIGNAL that displays a red light when you are not permitted to turn left. Where's the design failure in that? The driving error lies with the driver alone - there is nothing in the design that leads the driver to believe, erroneously, that a left turn is safe or permitted in the red light phase. Unless we have a new 'left turn on red' law that I'm unaware of.
If the same accident keeps happening again, and again, then it's a design failure and unsafe. Even if the experts can't see what is wrong with it! The law doesn't matter. A competent engineer must (by law) design with safety in mind, irregardless of the traffic laws.
