I worked as a traffic accident investigator for a few years. Part of my job was figuring out the timing of traffic lights and if they were the cause of an accident. Shortening yellow lights kills people, old people and big trucks dont stop very fast. This is the Florida government killing people for money.
The really sad part is if they were really clever they would shorten the yellow 1/2 a second but keep the whole intersection red for a 1/2 a second. That way they could rip off Floridians without killing them.
