Comfort and Convenience
Seating position is a personal matter: height, leg length and driving habits differ, so the position one driver finds natural can feel cramped or distant to another sharing the same car.
Safety and Driver Assistance
Knowing where the lights, wipers and demister controls sit before setting off means less searching later, since weather and traffic rarely wait for a driver to study an unfamiliar dashboard.
Multimedia and Connectivity
Keeping a phone charged on a long drive is an ordinary need in its own right, separate from making calls or playing music, which depend on whatever connection a car supports.
