Comfort and Convenience
Seating height is a matter of personal preference: some drivers want a raised view over traffic ahead, while others sit low for a more enclosed feel. Body proportions and long habit explain most of that difference.
Safety and Driver Assistance
Locating the wiper, lighting and hazard switches takes a minute while the car is still parked. Doing it beforehand means less searching through unfamiliar menus when weather or traffic changes.
Multimedia and Connectivity
Charging and audio are separate needs, since a phone can play music while its battery continues to drain, depending on which connection is used. Knowing which socket actually supplies power helps on longer drives.
