Comfort and Convenience
Seating comfort is personal: a cushion angle that suits a tall driver can feel awkward for someone shorter. People sharing a car therefore tend to want different seat and mirror positions.
Safety and Driver Assistance
Spending a minute before setting off to locate lights, wipers and demisters means those controls are already known when the weather turns. Preparation of that sort replaces a search with one deliberate movement.
Multimedia and Connectivity
A phone's battery drains quickest on long drives with navigation running. Where a charging outlet is available, keeping the phone powered stays a separate question from how calls or music reach the speakers.
