Comfort and Convenience
Cabin temperature is the classic point of disagreement: one person wants air moving, another feels a draught. Because comfort here is personal rather than measurable, most trips settle it through conversation and small compromises along the way.
Safety and Driver Assistance
A few minutes spent locating lights, wipers and demisting before setting off means less searching later, when attention is better spent elsewhere. Preparation is simply about knowing where things are while the car is still stationary.
Multimedia and Connectivity
Phones drain quickly when navigation runs for hours, so passengers often want somewhere to charge. If charging points are available, their position matters: a cable that reaches the back seat is more useful than one that stops short.
