Sadly I suspect that will not be the case. You need various sensors and computers to fill safety requirements (e.g AEB is now required on all new cars and I expect stuff like speed limit detection to become mandatory in the near future), let alone comfort and entertainment features.

Since most if not all of the necessary hardware is already in it's going to be pretty hard to keep manufacturers from collecting data - trends in smartphones and computers have shown people will accept a lot of data collection and ongoing subscription services, and I expect the car manufacturers have been taking note.
