Direct control vs abstract control vs intelligence interaction has been a long running topic in HCI. For the most part it has been evolving in funny ways (i.e. skumorphism used metaphors from direct control to execute abstract control). I think the design language will evolve slowly with the users at a speed roughly related to the adoption curve. It may tell users everything that the car is deciding to do now, and as confidence in the system increases with adoption, it will do less and less. That is why more advance self-driving car researchers are working on the harder problems of getting abstract and intelligent interaction with a car working. The real market problem is just telling you car "take me to the store" rather than just getting it to drive down a straight lane.
