Comfort and Convenience
Seating preferences follow height, build and habit: one driver sits upright and close to the wheel, another further back. The same seat can therefore feel quite different to two people sharing a car.
Safety and Driver Assistance
Finding the hazard lights, demister and wiper controls before setting off means less searching once traffic demands attention. A few minutes while parked is generally the easiest time to locate them.
Multimedia and Connectivity
Charging, calls and music are separate needs: a phone can be taking power without its audio playing through the speakers. Where a system covers each, knowing which is active avoids confusion.
