Comfort and Convenience
Preferred cabin temperature is a good example: some people travel comfortably in cooler air, while others chill quickly. Clothing, circulation and where someone is sitting mean one setting rarely suits every passenger equally.
Safety and Driver Assistance
Learning where the lights, wipers and demister switches sit before setting off means less searching later. A few stationary minutes spent adjusting mirrors and seating position leaves fewer decisions to make once the journey begins.
Multimedia and Connectivity
Phone battery is the usual concern on a long drive, since navigation drains it steadily. If a suitable charging point is available, keeping the cable within easy reach matters more than which socket type it uses.
