Comfort and Convenience
Seating preferences vary because people differ in height, build and habitual posture. A position that feels natural to one driver can leave another sitting too close to the wheel or too far from the pedals.
Safety and Driver Assistance
Knowing where the wiper, lighting and demister controls sit means they need not be searched for mid-journey. That kind of preparation is easiest while parked, when labels and markings can be read calmly.
Multimedia and Connectivity
Charging, calls and music are separate needs. A phone can be kept powered for navigation while audio plays, and where hands-free calling is supported it usually interrupts playback rather than replacing the audio source.
