I am OK with voice commands, though a common vocabulary for the important ones would be good (kind of like the way the main steering-column stalk controls are kind-of standardized), but the few weeks of familiarization with the touchscreen buttons is problematic, especially for anyone who frequently rents cars. Physical buttons that cannot be located by touch are no better than touchscreen buttons, though the flexibility of touchscreen buttons probably opens up the scope for implementing them badly.
