Comfort and Convenience
On a stop-start errand afternoon, people differ over how far to open a window because they dress differently and tolerate breeze differently. Some like extra air at lights, while others prefer a quieter, more closed cabin.
Safety and Driver Assistance
A quiet minute before leaving for the dry cleaner is useful for finding lights, wipers, and the horn, so those basics are not searched for once the journey has started.
Multimedia and Connectivity
A parked call to confirm a store pickup is a practical phone need. Music listening is a separate choice, and charging, if offered, is another matter still.
