Yeah exactly this.

FWIW while cars are essentially backdoored nowadays with all the cellular/OTA updates BS you can still disable it. I suspect this won't be an option in the near future, the way things are going.

I can't wait to see Hacker News comments in 2035 lamenting how they used to be able to "just use a bypass cable" to make their cars not phone home, by the time EVs and even general ICE vehicles have telemetry so deeply integrated with the vehicle it's impossible/illegal to be disabled.
