“Jarlstrom’s interest stemmed from a red-light-running ticket his wife received in 2013. He spent three years analyzing the method for calculating the duration of a yellow light and found that the formula failed to account for drivers who must slow down to make a legal turn.” Quacks like a duck.
I wouldn't be surprised if he uncovered something involving the timing of traffic lights that the state engineers knew about, but never did anything about it since it increased the chance of driver violations ever so slightly, and, therefore, more sources of revenue.
It's not cynical if it's true, you know.
