Hackable does not mean crackable. The best security implementations in the world are free software.

I'm not even a tiny bit convinced that making cars hackable would be a detriment to safety. Give me one example of that happening in literally any other sector.

You might have a point there, but I struggle to find any completely hackable product that is also safety-critical. Some airplane, nuclear reactor or some train, perhaps?

Any old car will do.

And new experimental aircraft, which are owner-built.
