Comfort and Convenience
Cabin temperature is a preference people rarely agree on: one passenger feels a draught where another feels relief. Clothing, recent activity and how long the journey lasts all shift what counts as pleasant on a given day.
Safety and Driver Assistance
A few minutes spent before departure, adjusting mirrors and checking that indicator and wiper stalks fall readily to hand, turns unfamiliar controls into habit. Preparation done stationary is preparation nobody has to improvise mid-journey.
Multimedia and Connectivity
Calls arrive mid-errand whether convenient or not, and answering while driving is a task best handled without holding a handset. Where hands-free functions exist, arranging them beforehand saves fumbling; music libraries and charging are separate matters.
