Comfort and Convenience
Cabin temperature is a good example of a preference with no correct answer. Perceptions of warmth differ with clothing, time of day and personal tolerance, so passengers often want something other than what the driver chose.
Safety and Driver Assistance
A stationary minute spent setting mirrors, seat and steering column, then checking what the dashboard displays, turns guesswork into routine. Preparation matters most in an unfamiliar car, where habits from a previous one may not transfer.
Multimedia and Connectivity
Taking a call without handling the phone is the need most people think of first. Whether that is possible depends on the connection in use; music playback and charging are separate questions with their own requirements.
