Comfort and Convenience
Cabin temperature is the classic point of disagreement: the same setting reads as pleasant to one person and stuffy to another, partly because clothing, seating position and airflow differ around the cabin.
Safety and Driver Assistance
Sorting out the basics before setting off — mirrors, lights, wipers, demist — is simply preparation: a stationary minute is the easy time to find them, rather than searching while passengers are waiting and traffic moves.
Multimedia and Connectivity
Charging is the need that shows up most on long trips, since a passenger's navigation or messaging drains a battery steadily. Where a power outlet or charging point is available, keeping a suitable cable aboard makes it usable.
