What protects US operators is not the task but the context: strong transit unions, decades-old signaling that must be replaced before automation is possible, and the political cost of removing a uniformed human from a car full of passengers. The surviving work is incident response, evacuations, door and platform judgment in crowded conditions, and reporting track or equipment defects.", "outlook": "Headcount holds in most legacy US systems through the 2030s because of union contracts and old signaling, but every new automated line or CBTC resignaling converts driving into monitoring and shrinks the operator roster.", "what_would_raise_it": { "levers": [ { "dimension": "liability_shield", "change": "A negotiated or legislated crew-size floor for automated operation — e.g. TWU Local 100 contract language or a state law of the kind New York considered requiring a credentialed attendant aboard every train, or an FTA State Safety Oversight Program Standard conditioning GoA4 approval on a certified onboard employee responsible for evacuation.
