Comfort and Convenience
Seating preferences differ largely because height and leg length change where the eyes and hands naturally fall. A position that suits one person can leave another reaching further or sitting lower than they would like.
Safety and Driver Assistance
Knowing where the wiper, lighting and demister controls sit before departure means those adjustments can be made without hunting for them later. A couple of minutes while parked is usually enough.
Multimedia and Connectivity
Phone battery life shapes longer journeys, so charging is a separate need from audio. Where a cable or pad is available, the phone stays powered whether or not it is also playing music or handling calls.
