Comfort and Convenience
Seating position is a good example: some people prefer to sit high with a clear view over the bonnet, others low and close to the wheel. Height, reach and habit all shape which feels natural.
Safety and Driver Assistance
Before a first long trip it is common to set mirrors, seat and steering position, and to check where the lights and wipers are. Preparation of that sort simply removes guesswork from the moment conditions change.
Multimedia and Connectivity
Keeping a phone charged on the move is its own need, separate from calls or music: navigation apps drain a battery over a long day. Where charging is available, the practical question is whether it reaches where the phone actually sits.
