Comfort and Convenience
Cabin temperature is a good example: some travellers prefer cool, brisk airflow, others a steady warmth. Body build, clothing and how long someone has been sitting all shape that preference, so a setting agreed early avoids constant adjustment.
Safety and Driver Assistance
Before setting off, it helps to locate the wipers, lights, hazard switch and demist functions while stationary. Preparation of this kind means fewer moments spent searching for something unfamiliar when weather or traffic changes.
Multimedia and Connectivity
Keeping a phone charged matters on long days, since navigation drains a battery quickly. If a suitable charging option is available, a cable that reaches the driver's seat is worth packing separately from any audio arrangement.
