Comfort and Convenience
Seating preferences differ because bodies differ: leg length, shoulder width and posture habits all change where someone wants to sit. A position one person calls upright can feel cramped to another.
Safety and Driver Assistance
Spending a minute with the wiper, light and mirror controls before setting off means fewer unfamiliar movements later. Preparation is easiest while parked, when nothing else is competing for attention.
Multimedia and Connectivity
A phone running low on charge during a long drive is a common annoyance; where a charging point is available, it keeps navigation usable. Charging is separate from calls or music playback.
