Comfort and Convenience
Some travellers like an upright seating posture for a long sit, while others prefer a more reclined angle. That preference is personal and can change with who is driving and who is riding as a passenger.
Safety and Driver Assistance
Before a pre-dawn departure, it helps to locate the horn, indicators, and lamp switches while the vehicle is still parked. That short walk-through is simple preparation, so those actions are not searched for after the trip has already started.
Multimedia and Connectivity
A passenger may want a spoken story or radio for the hours between stops, which is separate from placing a call. If audio playback is available, it can fill quiet stretches without involving the phone for conversation.
