Comfort and Convenience
Cabin temperature is a common comfort difference: one person may feel cold while another is warm, so the ability to adjust airflow direction or strength can settle the matter.
Safety and Driver Assistance
Practising indicator and brake pedal use in a quiet area before a long journey helps turn basic actions into habits, reducing the need to glance down at the controls.
Multimedia and Connectivity
Keeping a phone charged is often a practical concern on long drives; if a power socket is available, using it for a cable can keep the battery level stable without interrupting calls.
