Safety score liability

Data technology is increasingly deployed to assign safety scores to people and products. Could these scores be used to apportion liability for accidents? Instead of liability based on ad-hoc care level (the negligence rule), “safety score liability” imposes liability commensurate with the habitual propensity to behave unsafely. This article describes how such a regime works, the incentives it creates, and the barriers it faces. It demonstrates its application to the most common torts—auto accidents. Safety score liability offers a novel foundation for the notion of fault in tort law, with surprisingly strong incentives for care, and an effective scheme for compensating victims.
