Comfort and Convenience
Climate preferences vary widely because one occupant may want strong airflow while another finds moderate ventilation more agreeable.
Safety and Driver Assistance
Learning the basic mirror and seat adjustments before setting off can make frequent stops and parking maneuvers less distracting.
Multimedia and Connectivity
A passenger may want to play their own playlist during a commute; if an auxiliary input or similar option exists it allows that choice independently of the driver's phone.
