Comfort and Convenience
Some people like to keep a bottle in hand or on their lap, while others wait to drink until a stop. That preference differs because thirst and routine are personal, not shared.
Safety and Driver Assistance
Checking how the mirrors move before leaving a driveway lets a driver finish that setup while parked, rather than searching for the control once the vehicle is already rolling.
Multimedia and Connectivity
One listening need is pausing a playlist when the vehicle stops for fuel, so the same track does not skip ahead unheard. If playback is available, that pause is a simple habit, separate from taking calls.
