If you have a million stolen licenses, but on the road remain very few, say 1k. While there are say 100m other cars. If you now have 99% accuracy, you will read 990 stolen cars, and misread 1m plates. Since 1% of plates are stolen, you randomly hit 10k of those misreads into a stolen plate.
This is generally alwayd an issue with rolling out mass tests. If the thing you search is even rarer than your failure rate, most detections are errors no matter how good your test.
This is why we don’t just test everyone for diseases all the time even when it would be very cheap and simple.





















There’s not really a replacement for this one, it’ll likely be important later.
This is clearly the kind of thing you disown and nationalize, not blindly destroy.
