Mozilla released their studies, and I’m seeing a growing number of posts on the Internet about cars and the privacy nightmare they entail. I remember how this issue wasn’t talked about earlier because “just buy an older car” was still prevalent. I’m so happy that people are taking notice. Thank you to this community and Mozilla for the work they are putting in!
You don’t need a very old car, just one that is old enough the cellular network doesn’t work any more.
Some vehicles were made for 3g, and can’t go to 4g for example.
Just put a faraday cage around the antenna.
2g antenna sare still up and running. Every new generation is add on top of the previous like a new layer of the network. And telemetry can be collected through older gen network.
