Comfort and Convenience
Cabin temperature is a common point of disagreement: one person's pleasant warmth is another's stuffiness, and preferences shift with clothing, seating position and time of day. Agreeing on a setting early tends to prevent constant readjustment.
Safety and Driver Assistance
A few minutes spent locating mirrors, lights and hazard switches before setting off is worthwhile preparation, particularly in an unfamiliar car. Knowing where something sits means not hunting for it once passengers and traffic are demanding attention.
Multimedia and Connectivity
Keeping a phone charged matters most on longer trips, when navigation and messages drain a battery faster than expected. Where a suitable power outlet and cable are available, a passenger can handle this without involving the driver.
