Comfort and Convenience
Preferred cabin temperature varies widely, and a setting that suits the driver can feel stuffy to someone in the back. Build, clothing and how long a person has been outdoors all shift what counts as comfortable.
Safety and Driver Assistance
A few minutes before setting off, spent locating the hazard switch, the demister and the wiper stalk, means those things can be reached later without improvising. Preparation is about not learning a layout mid-traffic.
Multimedia and Connectivity
Phone battery is the common everyday concern, since navigation drains it over a long run of errands. Where a charging option is available, keeping the right cable in the car matters more than the format itself.
