Comfort and Convenience
Cabin warmth is a personal preference: one passenger may want cool air on a summer school run, while another prefers it milder on the same hop. Clothing and time of day change what feels right.
Safety and Driver Assistance
Before a dawn airport run, a quiet minute to find the lights, defroster, and horn means you are not searching on a dark driveway. That check is so you are not learning the layout after you have set off.
Multimedia and Connectivity
If a work call comes in while you wait outside school, answering without holding the phone is useful when that option exists, so the handset can stay in a bag. Charging and playing music remain separate needs.
