They don't need all the vision data -- likely what they're doing is running their beta self-driving features in the background all the time, and only send data back (1) when the driver's input differs dramatically from what the self-driver would have done itself, presumably because the driver saw something their software missed, and/or (2) when a driver gets in a crash (at which point they can check if their algorithm would have prevented the accident).

They just need to send back data from a few seconds before either of those scenarios to quickly accumulate a giant library of one-in-a-million edge cases they can test future algorithm tweaks against. I think it's a reasonable strategy.

This is a gross misrepresentation of what's happening with AP2. AP2 is not up to feature parity with AP1, but it's not true that "it's not active".

This article summarizes the latest AP2 software release: https://electrek.co/2017/03/30/tesla-autopilot-2-0-camera-8-...

I couldn't find a reference to this:"Tesla no longer sells cars with automatic driving capability." Can you point to one?

Search Google for "Tesla disables autopilot".

Thanks. I found that when they transitioned to Hardware2/AP2 they cut out most autopilot functionality, and since then have been gradually releasing updates that bring back that functionality.
