What each collision costs (KABCO comprehensive, USD)

Linear scale, so a fatal crash ($11.3M) visually dwarfs every other tier (about 950× a property-damage-only one). That is exactly why the severity mix, not raw collision counts, drives the dollar figure. Values: FHWA crash-cost guidance, fatal anchored to Blincoe et al.; used in the monetization step.
