The traffic light system in Houston is just retarded. Considering the left hand signal. Do they still think that we are idiots that we can't make up our mind to turn left if there IS NO ON COMING TRAFFIC!!!??? Can they see what other cities have done about their left turn signaling? For example almost all Dallas Left hand Signals are optional Yield & Protect, this saves valuable time for the commuters. Nothing is more frustrating then sitting on a red trying to turn and left and there is NO ONE in the on coming lanes. Just the other day, i sat at the red for 4 minutes, yes i counted, and there was no on coming traffic at all!!!
