Comfort and Convenience
Seating position is personal: height, reach and posture differ, so two people rarely settle on the same setup. Anyone sharing a car regularly finds it worth agreeing how quickly each driver can return to their own preference.
Safety and Driver Assistance
Before setting off, it is worth locating wipers, lights, demisting and hazard warning, since city weather and traffic rarely give time to search. Preparation is simply about removing one distraction from a journey that will bring others.
Multimedia and Connectivity
Battery level matters on days built from errands, because navigation drains a phone quickly. If charging is available on board, it is a separate question from how calls are handled or how audio reaches the speakers.
