Comfort and Convenience
Comfort preferences vary because people differ in height, build and the posture they settle into. A driver who prefers sitting upright and close to the wheel will arrange things differently from someone who sits further back.
Safety and Driver Assistance
Spending a few minutes finding the lights, wipers and demister before setting off means less searching once underway, when attention is better spent on the road than on locating an unfamiliar switch.
Multimedia and Connectivity
Keeping a phone charged through a long journey is a separate matter from playing music or handling calls. Where such functions are offered, each may depend on a different socket, pairing or menu setting.
