The other massively understated thing about Chicago's red light cameras is that Chicago, compared to other areas with similar or even much lower traffic volumes, has very few left turn lanes, and even fewer left turn arrows when they are there. As a result, the general population is habituated to only being able to turn left at the last second on a yellow signal, which complicates the short yellow timings even more.
