Comfort and Convenience
Cabin temperature is a good example of personal preference: some people are comfortable with cool air blowing steadily, others prefer warmth and gentle airflow. Shared journeys often mean negotiating a middle setting.
Safety and Driver Assistance
A few unhurried minutes while parked are enough to find the main switches and understand what the instrument panel shows. That groundwork belongs to preparation, and it need not depend on any particular equipment.
Multimedia and Connectivity
Hands-free calling matters mostly for keeping conversation from occupying a hand, which is unrelated to how music reaches the speakers or how a battery is topped up. Where such features exist, setup is usually one-off.
