Comfort and Convenience
Preferred seating height is a good example: some drivers want a raised view over traffic, while others sit low for a more enclosed feel. Body proportions and long habit shape the choice, so no single setting suits everyone.
Safety and Driver Assistance
Learning where the main controls sit while parked means less hunting for them later. Wipers, lights and demisting are worth locating first, since weather can change long before there is a convenient moment to look.
Multimedia and Connectivity
Keeping a phone charged through a long day matters separately from playing music over the speakers: where power is drawn from is one question, and how audio reaches the system is another. Calls add a third.
