Comfort and Convenience
Cabin temperature is a clear example of personal preference: a setting one person finds pleasant can feel stuffy or chilly to someone beside them, since clothing, build and where a person sits all differ.
Safety and Driver Assistance
Time spent before setting off locating the essential controls — lights, wipers, hazard switch, mirror adjustment — removes unfamiliar actions from the journey itself. Preparation of this kind is simplest while the car is stationary and nobody is waiting.
Multimedia and Connectivity
Charging is a need distinct from calls or music: on a long drive with navigation running, a phone battery falls steadily, so whatever charging provision a car offers is often used more than an owner first expects.
