Comfort and Convenience
On a morning of school drop-offs and errands, one occupant may want the cabin cooler while another wants it warmer, because heat comfort is personal.
Safety and Driver Assistance
Locating the hazard switch and window switches while the car is still on the driveway, before a night-time pickup, means those controls are already known when the stop is busy.
Multimedia and Connectivity
If a phone is nearly empty before a day of appointments, a cabin charging point, if fitted, can restore power for messages without involving calls or music.
