Comfort and Convenience
During a school run, some occupants prefer cooler air while others want a warmer cabin. That split is ordinary, because people feel heat and airflow differently.
Safety and Driver Assistance
When waiting in a dark car park for a night pickup, finding lights, wipers, and the demister first means those controls are already known before the car starts moving.
Multimedia and Connectivity
On a day of errands, a phone may need charging so it still works later. A cabin socket, if fitted, can cover that task without involving calls or music.
