Comfort and Convenience
Preferred cabin temperature varies widely: a setting one person finds pleasant feels too warm to someone else. Height and build also change where a driver wants to sit, so agreement is rare.
Safety and Driver Assistance
Spending a minute before departure locating the hazard lights, wipers and headlight switches leaves less to search for later. Preparation of this kind is simplest while parked, when nothing else demands attention.
Multimedia and Connectivity
Phone batteries drain quickly across a long journey, so a charging point matters independently of audio. Where hands-free calling is offered, it stays a separate function from how music reaches the speakers.
