Comfort and Convenience
Preferred cabin temperature is rarely unanimous: someone sitting in direct sun feels warm while a passenger in shade stays cool. Body size, clothing and how recently a person was walking outside all shift that sense.
Safety and Driver Assistance
Spending a moment with the main controls before setting off means less searching later — wipers, lights, demisting and hazard warning. Knowing where they sit helps attention stay on the road rather than the dashboard.
Multimedia and Connectivity
Long trips drain phone batteries, so it helps to know in advance how a passenger might keep one topped up. If charging outlets are available, agreeing who uses them avoids the usual mid-journey negotiation.
