Comfort and Convenience
Preferred seating position is personal: some drivers want a higher, upright view of the road, others a lower, more settled posture. Body proportions and the kind of routes driven most often explain much of that difference.
Safety and Driver Assistance
Spending a few minutes with wipers, lights, mirrors and hazard switches while parked means those actions later come from memory rather than from searching, so attention stays with driving rather than the dashboard.
Multimedia and Connectivity
Keeping a phone charged during a run of errands is its own need, separate from calls or music. If a charging point is available, a cable that reaches the usual stowage spot makes topping up routine.
