Comfort and Convenience
A preferred seating position varies from one person to the next, since height, reach and posture all differ. A setting that suits one driver can feel wrong to another, so a shared car usually involves readjusting before setting off.
Safety and Driver Assistance
A couple of minutes spent locating the hazard switch, the demister and the wiper controls before a journey means they are not being hunted for at an awkward moment later. Preparation of that kind is a sensible habit in any car.
Multimedia and Connectivity
A phone battery often runs low over a long day out, so keeping it topped up matters in its own right. Where a car provides a power outlet, that need is covered separately from calls or listening to music.
