"Traffic safety is equally important for poor people and for people with money. But traffic fines, as they are typically imposed, inflict far more pain on poor people." The first part of that is quite an assertion. Richer people probably have newer cars (thus benefiting from newer safety features), better maintained cars, bigger cars, live in areas with less traffic, have better access to healthcare, and can afford to take time off due to injury. In addition, their jobs overall are probably less physically demanding. I wonder if that's a good part of why they aren't doing things that would cost taxpayers money, like re-engineering roads to improve safety and lower speeds?
