I'm kind of irritated that the article doesn't say anything about probabilities.

Given they have enough data, at some point it's perfectly reasonable to have cars with 5+ crashes per 12 months - just because of chance.

This is exactly why statistics was invented, damnit!

I think “in the exact same way with all the known indicators of insurance fraud” adds a couple orders of magnitude to the expected by-chance odds.
Well they do say they calculate propensity scores, but the whole language of the blog post is very hand-wavy. Warning over and over again that something is not causal proof, and then dramaticizing it as if it were proof is just unprofessional.

If you have a fraud model, just show the model and the data and the validation - everything else is marketing fluff.
