Comfort and Convenience
Preferred cabin temperature is a common point of disagreement on long trips, since people differ in clothing, activity and how much airflow they like directed at them. Agreeing a setting early avoids constant adjustment.
Safety and Driver Assistance
Before setting off, it helps to locate wipers, lights, mirrors and hazard switches while parked. Searching for an unfamiliar control mid-journey is a distraction that is easily avoided with a few minutes' preparation.
Multimedia and Connectivity
Phone battery drain matters most on long drives, because navigation apps run continuously. If a charging point is available, keeping a suitable cable packed means the phone stays usable on arrival, not only en route.
