But there’s one aspect of Chicago’s traffic-camera program (and traffic enforcement in general) that’s problematic from a social justice standpoint: the fine structure is regressive. Chicago doles out a $100 ticket for running a red light or speeding at 11 mph over the limit. Since the tickets cost the same whether you’re rich or poor, lower-income people are charged a higher percentage of their income than rich people are. A $100 penalty may be about right for making middle-class people think twice before breaking the rules of the road. But for a person who’s barely making ends meet, it could be a major hardship.
