Comfort and Convenience
Cabin temperature is a common point of disagreement, since people differ in what feels warm. A setting that suits the driver may feel cool to someone sitting behind them.
Safety and Driver Assistance
Locating the lights, wipers and hazard switch while parked means less searching later. Unfamiliar cars differ in where these sit, so a brief look before setting off is worth the minute.
Multimedia and Connectivity
Phone charging and audio playback are separate needs. A cable may carry both power and sound, while a wireless link usually handles calls and music only, leaving charging to a separate socket.
