Comfort and Convenience
Seating preferences differ largely because of body proportions: a taller driver tends to want the cushion further back and lower, while a shorter one sits closer to reach the pedals easily.
Safety and Driver Assistance
Locating the wiper, lighting and mirror controls while parked means less searching later, since a first drive in rain or fading light is an awkward time to learn where each switch sits.
Multimedia and Connectivity
Keeping a phone powered is a separate need from playing audio. If both run through one cable, a single port covers them; if sound arrives wirelessly, the phone still needs its own power.
