Comfort and Convenience
Cabin temperature is a good example: one person wants air moving constantly, another finds any draught unwelcome. Height and driving posture change this too, so shared cars often need a compromise agreed between regular occupants.
Safety and Driver Assistance
Learning where the essentials sit while parked, rather than at speed, is simple preparation. Anyone borrowing or newly buying a car benefits from a few quiet minutes with the switches before setting off.
Multimedia and Connectivity
Keeping a phone charged on the move is its own need, separate from calls or music. If a power source is available and reachable, the phone can stay topped up without cables trailing across the cabin.
