Comfort and Convenience
Cabin temperature is a common point of disagreement: what feels pleasant to a driver in a jacket can feel cold to someone sitting still in the back. Body size, clothing and activity all shape it.
Safety and Driver Assistance
Spending a moment with the basic controls before setting off, such as lights, wipers, mirrors and the hazard switch, means you are not searching for them later, when passengers are talking and the road needs attention.
Multimedia and Connectivity
Phone battery is the usual concern on longer trips. Where a car offers a charging point, a passenger can keep a navigating phone alive; that is separate from how calls are answered or music is played.
