Behavior.

What the driver does — the hinge between setting and crash.

The BEHAVIOR group: distraction, impairment, fatigue, speed choice and restraint use — the avoidance-stage hinge where only a change in behavior reaches the crash chain. FARS records the police-coded residue; true behavior lives in the Research / naturalistic layer.

Known blindspots — future work

What we do not yet have. These are explicit so the gaps stay visible and become the agenda for future DB and knowledge-integration work.
