Comfort and Convenience
Preferred cabin temperature varies widely: one passenger wants steady warmth while another reaches for cooler air within minutes. Clothing, the time of year and simple personal habit all shape where each person sets the dial.
Safety and Driver Assistance
Adjusting mirrors and seat, then checking which stalk does what, belongs at the start of a journey rather than in traffic. Preparation of this kind costs little and is easiest done while stationary.
Multimedia and Connectivity
Taking a call without holding the phone is a need of its own. Where a hands-free function exists, it handles conversation; music playback and keeping the battery topped up remain separate questions with separate answers.
