Not directly related to the car situation, but the last time I bought a TV my first question was whether non-smart TVs exist. They do, but they're not worth the effort and my best option was to not connect the TV to the network.
It sounds like it's no longer even an option to buy a car that doesn't come with a bunch of uplinks to the car company, maybe to the insurance company airplane-black-box-style, etc.
Some IoT devices now are programmed to reach out to public or known (ISP) wifi networks and connect automatically without your knowledge or consent. This is what it looks like when your government is by and for corporations.

If the tech exists, it will be abused.
