Comfort and Convenience
Some passengers like a window cracked open for fresh air on a warm afternoon, while others prefer it shut to keep draughts off their neck. That preference often changes with the weather and who is in the car.
Safety and Driver Assistance
A moment on the driveway to locate the indicator stalk and hazard switch leaves those actions known later, instead of being hunted in a moving queue.
Multimedia and Connectivity
On a repetitive commute, many people want background music or a spoken programme. If playback from a phone is available, that can cover it; otherwise a radio station meets the same listening need.
