I believe green's claim is nothing more than that HW2/3 Teslas aren't recording video or object detections all the time and uploading all of them.
I think continuous recording is what green interprets as “shadow mode”, but I don't interpret it that way.
I interpret shadow mode as being just another set of event-based triggers of the sort that green has confirmed exist. In the context of shadow mode, events that trigger snapshots are likely disagreements between the trajectory outputted by the Autopilot planner and the car's trajectory while being fully human-driven.
Your beliefs are groundless. Green has explicitly debunked your interpretation of his own findings. You have no car or primary sources.
