Comfort and Convenience
How much fresh air people want on a short hop to the shops differs, because some like a breeze while others dislike moving air on their face.
Safety and Driver Assistance
Becoming familiar with demister and lighting controls on the driveway before a foggy morning run to work leaves those actions out of the first junction. The value is preparation while the car is still at rest.
Multimedia and Connectivity
If a phone battery is low during a day of appointments, a cabin charging point, when fitted, can keep the handset available for messages between stops.
