1. EOL - I'm wondering how "vintage" and "obsolete" models will be handled. Let's suppose parts go NLA, it would be curious to see if mobile apps would still work, which parts can be changed, and what feature(s) would stop working.
2. Tesla's ability to disappear or introduce features and changes in behavior over time
3. Ability or inability to stop, pause, or revert software updates
4. E2EE
5. Encryption of on-board data at rest
6. Encryption of phoned home data at rest
7. Telemetry data on-board
8. Telemetry data phoned home
Perhaps there ought to be a r2r requirement of open source schematics, bill of materials (BOMs), and firmware for vehicles no later than when parts become NLA.
