Comfort and Convenience
Cabin temperature is largely a matter of personal preference, and airflow that suits the driver can feel too cool to someone sitting further back. Settling on a setting early tends to save repeated adjustment along the way.
Safety and Driver Assistance
Knowing where the essentials sit — lights, wipers, demisting, hazard switch — before setting off means less hunting once under way. A minute spent locating them while parked is easier than working it out with passengers aboard.
Multimedia and Connectivity
Keeping a phone charged matters on longer trips, since navigation drains a battery steadily. Where a suitable power source is available, agreeing in advance who uses it avoids a cable being passed back and forth mid-journey.
