If you’re willing to do a little bit of work you can often remove the cellular radio from some modern cars to remove the data collection connectivity, not sure if it’d still be buffered on the device still but it’s a step in the correct direction. I’ve read about this in some modern BMWs so it might be worth a bit of googling if you have a particular modern car you are interested in. Or if no one else has done it with a particular model you could also blaze your own path here.
