Comfort and Convenience
A comfortable seating position is a personal matter, since people differ in height and preferred posture, and what feels supportive to one person may not to another.
Safety and Driver Assistance
Before heading out, it is useful to spend a little time locating the controls for lights, wipers, and ventilation so they can be reached without taking attention from the road.
Multimedia and Connectivity
Keeping a phone charged on a long trip is a common need, and if there is a suitable socket, having a cable already in place can prevent interruptions to navigation or music.
