Comfort and Convenience
Cabin temperature is a common point of disagreement, because people arrive dressed differently and sit in different places relative to windows and vents. A setting that suits one seat may feel too warm or draughty in another.
Safety and Driver Assistance
Finding lights, wipers and demisting before setting off means they are not searched for later, when conditions have already changed. A short check while stationary is also the easy moment to set mirrors and seating position.
Multimedia and Connectivity
On longer journeys a phone used for navigation drains quickly, so keeping it charged can be the most practical concern. Where a charging point is available, passengers can usually manage it without involving the driver.
