Of all the innovations in modern auto design, I'm not sure that's the one I'd go for. IIRC, a CAN bus design is essentially a jazz model for connecting different subsystems with no built-in security standards. For some reason, I'm not sure externally connected hardware, OTA-updated software, a vehicle's essential mechanical control systems, and implicitly trusted access from everywhere to everything via a centralised bus is a good combination. Some of the relevant technology is patent-encumbered as well, which is rarely an ideal basis for standardisation and interoperability IMHO.
