Comfort and Convenience
Cabin temperature is the classic point of disagreement: what one person calls pleasant, another finds stuffy or cold. Differences in clothing, seating position and sensitivity to airflow explain why agreement usually takes a short conversation.
Safety and Driver Assistance
Spending a minute with the basic controls before setting off — lights, wipers, mirrors, ventilation — means fewer unfamiliar moments later. Preparation is easiest while parked, when a passenger can help and nothing else demands attention.
Multimedia and Connectivity
Keeping a phone charged matters most on long trips, when navigation drains a battery faster than expected. Where a charging option is available, it is worth agreeing early whose phone gets it.
