"Don't like OBD II"
So you'd prefer to be held to ransom by a manufacturer's proprietary interface to diagnose problems with your car? Unless you want to go back to carburettors and dumb (no anti-lock) brakes (why not go the whole hog and abandon disc brakes too) you need a way to talk to the car's systems and using the same interface makes it easier for non-franchise dealers to work with vehicles.
