Comfort and Convenience
Comfort preferences vary because people differ in height, build and driving habits, so a seating position that suits one person may feel wrong to another. Anyone sharing a car usually spends a moment finding their own position before setting off.
Safety and Driver Assistance
Spending a few minutes with wipers, lights and mirrors while parked means those actions are already known when conditions change, so attention can stay on the road rather than on searching for a switch.
Multimedia and Connectivity
Keeping a phone charged on longer journeys is a common need, separate from calls or music. Where a charging point is provided, knowing which cable it takes saves rummaging once the trip has begun.
