Comfort and Convenience
Cabin temperature is a good example: some passengers prefer cooler air moving steadily, others a warmer, calmer setting. The difference comes from clothing, time of day and simple habit, so agreement inside a shared car takes negotiation.
Safety and Driver Assistance
Spending a few minutes before setting off to locate lights, wipers and demisting is sensible preparation. Doing it while parked means these basics are already known when weather or traffic changes later in the journey.
Multimedia and Connectivity
Keeping a phone charged during the day is a separate need from playing music or taking calls. If a charging point is available and reachable from the driver's seat, the phone stays usable at journey's end.
