Comfort and Convenience
Cabin temperature divides people more than almost anything else. One passenger feels comfortable in cool air while another wants it warmer, which is why agreeing on a setting early avoids repeated adjustment.
Safety and Driver Assistance
Mirrors, seat and steering adjustment are best set before setting off rather than at the first junction. A few minutes stationary also reveals which warning lights are lit and what the instruments show.
Multimedia and Connectivity
Taking a call on the move is a common need, and hands-free operation exists so the phone stays out of your hands. Whether that is available, and how it is set up, varies.
