That last but is almost NMEA 2000, which standardizes exactly that kind of information, but in boats. It's old enough that they based it on CANbus, but there are many repeater products to add IP devices (Ethernet, Wi-Fi, Bluetooth) to the network.

ETA: By which I mean to say, plenty of designs already exist in the marine market which could be used to bridge a car's CANbus to consumer devices, if they wanted to.
