Comfort and Convenience
Seating position is a good example: some people like sitting upright and close to the wheel, others further back with arms extended. Height, leg length and habit all feed into that preference.
Safety and Driver Assistance
Before setting off somewhere unfamiliar, it is worth a few stationary minutes locating lights, wipers, mirrors and demisting. Knowing where they sit means you are not searching for them once the journey has started.
Multimedia and Connectivity
Keeping a phone charged on the move is a routine need, particularly when it is running navigation. Whichever charging options are available, what matters is reaching them without the cable crossing controls.
