It was several years before I was completely comfortable upgrading my iPhone without backing it up first, and Apple had decades of system software experience and complete control over the hardware.
Auto manufacturers are much, much worse than Apple at software, and I suspect they have less confidence all of their embedded electronics work correctly under all circumstances, although that’s just speculation on my part. From what I’ve heard about canbus, it’s a bit of a mess.
Anyway, I can completely understand why traditional auto makers are less comfortable allowing a car to be updated anywhere at any time, and why they might be less competent at securing the update mechanism.
