Comfort and Convenience
Preferred cabin temperature varies widely: what one person finds pleasant another finds stuffy or cold. Clothing, activity and the time of day all play a part, so any setting tends to be personal rather than universal.
Safety and Driver Assistance
Setting mirrors, seat position and lights before moving off is quick, and doing it while stationary avoids fiddling later. In an unfamiliar car, a minute spent locating the essentials is usually a minute well spent.
Multimedia and Connectivity
Keeping a phone charged on a long drive is a practical need in itself, separate from calls or music. Where a charging point is available, knowing its location before setting off saves searching mid-journey.
