Part of the reason cars have gotten more reliable in recent decades is due to this sort of standardization and refinement. What would you replace it with? If you replaced CAN, you still would need an in car network of some sort. It would have its own layer of security issues to worry about. Mechanics/Service centers would need an entirely new suite of diagnostic tools, this isn't just something you can quit using.

> What would you replace it with? Individual wires transmitting analogue signals; differential voltage or current loop, depending on application. Add a bunch of RC filter networks on either side to limit the bandwidth to the kind of signals going over the wire and you got a pretty tight, hardwired system.
