Comfort and Convenience
Seating height preference is a good example: some drivers want to sit high with a clear view forward, while others prefer a lower, more enclosed position. Build, habit and the kind of roads someone drives all feed into that.
Safety and Driver Assistance
Before setting off somewhere unfamiliar, it helps to know where the essentials are: lights, wipers, demister, hazard switch. Locating them calmly while stationary means less hunting later, when attention is better spent on the road.
Multimedia and Connectivity
Keeping a phone charged on a long day is its own need, separate from calls or music. If a car offers a charging point within reach of the driver, the cable simply stops being something to think about.
