Comfort and Convenience
Preferred cabin temperature is a good example: some travellers settle best in cooler air, while others dislike a draught. Height, clothing and where someone sits all shape that preference, so agreeing on it early helps.
Safety and Driver Assistance
Knowing where the basic controls sit, such as lights, wipers, demist and the hazard switch, is worth a few unhurried minutes while parked. Searching for them later divides attention at the moment the road asks for it.
Multimedia and Connectivity
Phone charging is the plainest need on a long drive, since navigation apps drain a battery quickly. Whether power arrives through a cable or a pad, it helps to know which outlets stay live while driving.
