Comfort and Convenience
Preferred cabin temperature is rarely the same for two people: clothing, time of day and simple personal tolerance all shift it. A setting that feels pleasant to the driver can feel cool to someone in the back.
Safety and Driver Assistance
A few minutes stationary is enough to locate lights, wipers, hazard switch and mirror adjustment. Doing that before setting off means the first roundabout or sudden shower is not also the first search for a control.
Multimedia and Connectivity
Keeping a phone charged on a long day matters separately from playing music or taking calls. If a charging point is available and reachable from the driver's seat, the phone stays usable at the end of the journey.
