I would love a car to have a central joystick, 100% drive by wire, pull back to accelerate, push forward to brake, tilt left/right to steer, all configurable with regards sensitivity, resistance feel (progressive/linear etc). No problems with left/right hand drive when it's centrally located between the seats. Display in the centre that can be tilted to the left or right depending on which seat the driver chooses or simply use heads-up display. Surprised it's not on some upmarket cars yet. Steering wheels are so outdate as are floor mounted pedals.
