Comfort and Convenience
Seating preferences follow height, build and how someone likes to hold the wheel, so a position that suits one driver rarely suits the next person sharing the same car.
Safety and Driver Assistance
Finding the lights, wipers and hazard switch while still parked means less searching once the car is moving. Preparation of this kind is simply part of settling into an unfamiliar cabin.
Multimedia and Connectivity
Charging, calls and music are separate needs. A cable keeping a battery topped up says nothing about whether audio or hands-free calling is routed through the car, since each is set up on its own.
