Widely used for assessing injuries in motor vehicle accidents. Clearly not linear – Faigin [1976] shows average societal costs per fatality and injury in 1975 US$.

AIS may not be linear, but Injury Severity Score and Log Number of Patients seems to have a good linear relationship [Baker and O’Neill, 1976].
