Comfort and Convenience
Seating position is a personal matter: height, leg length and posture differ, so two people rarely settle on the same setup. A driver who wants a clear view forward may sit differently from one who prefers a reclined posture.
Safety and Driver Assistance
Learning where the basic controls sit before setting off is simply preparation. Lights, wipers and demisting may be needed at short notice, so their location is worth noting while the car is still parked.
Multimedia and Connectivity
Phones lose charge over a long day, so a power source in the cabin matters most on longer journeys. If a car offers charging, that is a separate question from how calls or music reach the speakers.
