The widespread implementation of automatic traffic enforcement cameras in China objectively has decreased traffic violations. Compare driving in China in 2008 to 2024. It is a night and day difference.
I agree with your assessment about American traffic enforcement being more about collecting an informal tax than actually being about improving road safety (see: speed traps). In the UK (which this article is about), the speed cameras do flash (and thus provide immediate feedback).
