Another thing to point out is that Autopilot and FSD (Full Self-Driving) are separate functionalities and subscriptions, and it was not mentioned whether Autopilot was purchased or not, Autopilot has a couple of features like Traffic Aware Cruise Control which sets the speed based on the cars in front of you, and Autosteer which keeps the car in-lane, considering how old these people are, is it possible that they've mistaken that for FSD?
Edi: Wait, Elon did mention Autopilot was not enabled, and it would requires lines to be enabled, nevermind
