Comfort and Convenience
Preferred cabin temperature is a good example: one person runs warm and wants air moving, another finds the same setting chilly. Errand driving involves repeated stops, so the choice often reflects the weather and how often doors open.
Safety and Driver Assistance
Preparation is worth extending to the things needed in a hurry: hazard lights, the horn, the release for the tailgate or fuel flap. Finding them once, calmly, beats improvising while double-parked outside a shop.
Multimedia and Connectivity
Calls are their own need. If hands-free telephony is set up in advance, a conversation can carry on through the speakers; if not, the sensible option is to let it ring and call back once parked.
