This was a tip to OP, in case he wasn’t aware. Insurances will use any pretext to weasel out of their contractual obligations.

I made sure my car doesn’t come with a cellular modem. But I didn’t knew about the pressure sensors.

Your car insurance might be interested to know this fact.

Unfortunately, I do. And they lock you in to licensed vendors just for your seasonal tyre change.

Looks like my next car is going to be an antique.

Reproducible builds and lack of telemetry, plus hardening against compromise (by any actors) is my personal use case. I only run free/libre infrastructure privately, and hope to move on to open/libre hardware in future.
