Comfort and Convenience
Cabin temperature is a common point of disagreement on shared journeys. People differ in how warm they like to be because of clothing, where they sit relative to windows, and simple personal tolerance.
Safety and Driver Assistance
Spending a few minutes with wipers, lights, mirrors and hazard switches before setting off means less searching later. Preparation is easier when the car is parked than when passengers are talking and the road demands attention.
Multimedia and Connectivity
Phone battery runs down quickly on long trips, especially with navigation running. If a charging point is available, agreeing early who uses it avoids a scramble; charging is separate from calls or music playback.
