Comfort and Convenience
Preferred cabin temperature is a good example. Some travellers want cool air moving constantly, others feel a draught quickly, and differences in clothing, build and seating position mean one setting rarely suits everyone, so agreeing early helps.
Safety and Driver Assistance
Before setting off, it is worth locating lights, wipers, demisting and hazard switches while parked. Learning them under no pressure means less searching later, when attention is better spent on the road ahead.
Multimedia and Connectivity
Phone battery is the usual concern on a long drive, since navigation drains it steadily. If a charging point is available and the right cable packed, that need stays separate from calls or music.
