Comfort and Convenience
Cabin temperature is a common point of difference: people arrive dressed differently, sit in different parts of the car, and feel draughts and sunlight unevenly, so a setting that suits one passenger can feel wrong to another.
Safety and Driver Assistance
Learning where the essential controls sit before setting off, from lights and wipers to demisting and hazard lights, means less searching later, when attention is already divided between the road, the route and conversation in the cabin.
Multimedia and Connectivity
Phone battery drain is an ordinary concern on longer trips, since navigation and screen use consume power steadily. Where a charging option is available, knowing which port or pad it uses saves rummaging mid-journey.
