I wonder how many false positives the algorithm caused. They also called it an "AI system", but from the article it looks more like a statistical model that assign a risk score to every attribute (age, location, when, duration, ecc) and then do sum/weighted average. If the sum/weighted average are above a threshold, the reservation is flagged.
