Comfort and Convenience
Cabin temperature is a common point of disagreement. Passengers arriving from a heated shop feel warm while the driver has been sitting still, and personal tolerance for airflow on the face varies widely between people.
Safety and Driver Assistance
Preparation is most useful when someone drives a particular car only occasionally. Checking where the gear selector, parking brake and light controls sit before moving off means fewer questions to answer once traffic is moving.
Multimedia and Connectivity
Calls arrive mid-errand: a change of plan, an extra item to collect. Where a car supports hands-free use, routing a call through the speakers avoids handling the phone at all.
