The law should apply equally to everyone. The sole purpose of the legal system isn't only to provide deterrence. Fairness and equal treatment under law are cornerstones of the legal system. Some discrepancies make sense (e.g. higher bail amount for someone with means as an incentive for them to show up to court), but this is a huge overreach IMO.
Also begs the question, do wealthy people speed more than non-wealthy people? Do they need a deterrence?
> The overall TA mortality rate was 26.6(95% CI 13.4, 39.8) per 100,000 person-years, which was almost three times higher in men than that for women (40.4 vs. 12.1 per 100,000person-years). Lower economic level was associated with increased incidence and mortality of TA.
Optimizing for deterrence maybe means charging poor men a larger ticket. You see how this way of thinking is wrong?
Also imagine having to disclose your entire financial status to some court because you got a speeding ticket? It's a gross violation of privacy.
