Comfort and Convenience
On a winter school run, some people feel comfortable in a warmer cabin while others prefer cooler air for the same short trip, because temperature preference is personal.
Safety and Driver Assistance
Becoming familiar with the demister and washer controls before an early highway trip is useful preparation, because spray and mist tend to appear after the journey has already started.
Multimedia and Connectivity
On a long intercity run, a podcast can fill quiet stretches. If audio can play through the car speakers, the phone can stay in a bag instead of being held.
