Comfort and Convenience
Preferred seating position is one example: some people settle close to the wheel with a fairly upright back, others further away and more reclined. Build, reach and personal habit all shape what feels natural.
Safety and Driver Assistance
Learning where the essential controls sit, among them lights, wipers, demisting and hazards, is worth doing while parked. Searching for them later, in rain or fading light, turns a small task into a distraction.
Multimedia and Connectivity
Keeping a phone charged matters most when it doubles as the navigation screen, since mapping drains a battery quickly. If a suitable cable and power source are available, a long stage costs nothing in charge.
