You're overthinking this. People run red lights because they are impatient and don't get punished for it. There must be a 1 in 1000 chance of actually being caught. Maybe even better odds actually. During commute traffic in my area, without fail people will run the red lights, usually 2-3 cars minimum every single cycle.

Traffic code is unenforceable by current methods. That's the place to start. I for one am all in favor of the idea of red light cameras however, they were shown to actually cause more accidents. Go figure.
