>Take out the cellular modem? Next one requires connectivity to drive the car and so forth.
Find the cellular antenna and replace it with a dummy load. The car will think it's sending the data just fine but all it's doing is turning radio waves into heat.
I personally am, but there's only so much I can do. I am involved in our regional planning commission for transportation, and routinely write letters and call my representatives. I may donate some money to some of our local transportation organizations, but I'm not sure that's a good use of money yet so I haven't.
I agree with you in general though that public policy is failing. Specifically it's failing here where we continue to engage in and direct poor public policy positions because the government is very entrenched and addicted to spending taxpayer dollars. Asking the public to continue to play a catch up game of voiding their car warranty instead of actually solving the problem via policy is, in my view, simply not going to work.
And so on and so forth up until it’s just not worth the hassle as it even is today for most people. This isn’t a good problem to be solved with hacking. It’s a public policy problem.
