In Dallas they were caught decreasing the length of the yellow light. This gives drivers less time to react resulting in more revenue for the private company.
Here in Florida they just passed a state law allowing these. Despite that several cities had already installed them and were handing out tickets they were legally prohibited from issuing.
Whats so hard about putting a cop at a light to hand out tickets? Seems people would learn their lesson and stop running red lights.
Park an empty squad car and you’d get the same effect. Moving it every once in a while.
