Random sampling over time is substantially as effective as having someone enforce the law 100% of the time. It's something like how randomized algorithms can be faster than their purely-deterministic counterparts, or how sampling a population is quite effective at finding population statistics.

It feels less fair though. When everyone is driving x mph over the limit but only you get pulled over, it sucks. So I agree for efficiency of enforcement, but I'd rather see 100% enforcement (automated if possible), with more warnings and lower penalties.

  • It's only unfair if the innocent are punished. Lot of murders go unsolved. Does that mean the murderers that do get caught are treated unfairly?

    • That's a pretty extreme example, maybe the idea doesn't hold as much there. But yeah, if 99% of murders weren't prosecuted, the 1% who get charged might feel like they were singled out (and maybe they were, because of some bias or discrimination). Again, 100% enforcement is better.

  • It doesn't just "feel" less fair, it often is -- bc it's not truly random, it's selective enforcement which leads to things like "driving while black".

  • The problem with 100% enforcement is it doesn't allow law enforcement any discretion, and then you end up having to actually officially change the speed limit which would probably never happen

    • Definitely true in practice, but I don't think we want discretion. What I mean though is as a deterrent, you can either have a "fair" fine that's enforced 100% of the time, or 2x the "fair" amount with 50% enforcement, etc. When it's 100x the "fair" amount with 1% enforcement, and you see everyone else not being enforced, it feels unfair.
