Please keep OTA updates away from from my Grenadier.
If someone bricks my car, I want it to be sitting in a service bay. Vehicles have had surprise downgrades and partial cripplings by OTA updates. Recently, Polestar and Rivian. (New and inexperienced carmakers ... see a pattern that INEOS matches?)
When you allow Authorized Entities to reconfigure/upgrade/downgrade/disable your vehicle, you're basically allowing Anyone Who Discovers The Key to do it. Best case, it's only a good-intentioned but clumsy manufacturer. Worst case, it's warrantless law enforcement, three-letter-agencies, hackers, car thieves, and malicious jackasses.
If you build a door, assume keys for its lock will be found and you can never lock it properly again.
