I already accept a lot of places that I should let machines handle a task for me. I drive an automatic transmission rather then shift myself. I have traction control that overrides my foot to give me better control of the car. I fly in planes that are mostly flown by autopilot.
Assisted driving will only be a short stopgap. It will be quickly gotten rid of because of cost to maintain two systems and because the ugliness of a "drivers seat". Interiors will look nothing like they do now. There will be no drive-shaft (fully electric) so no big bump or center console in middle of car. No steering column, no mirrors and a completely different arrangement of seats then now.
In other words a fully automated car looks nothing like an assisted driving car. I doubt people are going to want to pay more and sit in less comfortable cabin, just for the opportunity to override the computer driver.
