Comfort and Convenience
Cabin temperature is rarely agreed on by everyone aboard. Preferences shift with clothing, where someone sits relative to the sun, and simple personal habit, so a setting that suits the driver may feel wrong two seats away.
Safety and Driver Assistance
Learning where the essentials sit, such as lights, wipers, hazard switch and mirror adjustment, is easier stationary than at speed in the dark. A few minutes in the driveway is a sensible habit before any unfamiliar car covers distance.
Multimedia and Connectivity
Phone battery drains faster on the road than at home, since navigation runs for hours. If a charging point is available and a suitable cable is packed, arriving with a charged phone is less a matter of luck.
