Comfort and Convenience
Cabin temperature divides opinion on a long trip more than almost anything else, since one passenger's comfortable warmth is another's stuffiness. Tolerance varies with clothing, metabolism and where someone sits relative to the vents.
Safety and Driver Assistance
Time spent stationary at the start, with mirrors set, the seat positioned and any menu settings sorted, means fewer things to work out in motion. Controls used rarely, such as rear fog lights, are worth locating in advance.
Multimedia and Connectivity
Calls taken on the move are a common need, and a hands-free arrangement keeps them from occupying a hand. Whether that works through the car's own system or a separate holder depends on what is available.
