Comfort and Convenience
Some travellers want a jacket or blanket within reach once underway, while others prefer a clear lap and an uncluttered seat. That difference comes from how people dress and how they like to sit, not from one shared habit.
Safety and Driver Assistance
Before a dawn start, it helps to know which stalk or switch works the headlights and wipers, so those choices are already settled. That is simple preparation for the first minutes of a trip, not a claim about later events.
Multimedia and Connectivity
A passenger may need to take a short call about a meeting time while travelling. If a hands-free calling function is present, that call can stay separate from whatever music someone else may choose to play.
