I am definitely against the newest measures taken by car companies, e.g. Porsche completely covering the engine (and voiding warranty should you access it) save the oil reservoir, on the newest 911s. There is also something missing from my metaphor which is that even when the parts no longer exist, the car can still continue to run until it breaks down, rather than being remotely killed due to an external signal separated from the car itself (e.g. servers shutting down and triggering some switch in the code).
