Comfort and Convenience
Cabin temperature is the classic point of disagreement: what one person finds pleasant, another finds stuffy or chilly. Differences in clothing, seating position and simple personal sensitivity mean a single setting rarely suits everyone.
Safety and Driver Assistance
Learning where the essentials sit, such as lights, demisting and the hazard switch, is best done while parked rather than in traffic. Preparation of this kind is simply about not needing to search for something at an awkward moment.
Multimedia and Connectivity
Keeping a phone charged matters on long trips, since navigation drains a battery quickly. If a charging point is available and reachable from the passenger seat, the person not driving can manage it.
