> Modern electronic cars use a single bus (CAN bus) that connect all electrical systems. The brakes, the engine, the wipers, the stereo... Not true. The automotive bus architectures I know first hand (admittedly far from all of them of course) have multiple CAN buses, plus other bus technologies as well (MOST/LIN/Ethernet). I don't think it would even be possible from a bandwidth/latency standpoint to push everything across a single CAN bus.
