Comfort and Convenience
Seating position is a personal preference: drivers differ in height, leg length and how upright they like to sit, so the setting one person finds natural can feel wrong to the next. Preferences also shift with journey length.
Safety and Driver Assistance
Knowing where the lights, wipers, demister and hazard switch sit before setting off means less searching later, when attention is better spent on the road than on unfamiliar buttons. A few stationary minutes covers most of it.
Multimedia and Connectivity
Keeping a phone charged on longer trips is a common need, and it is separate from audio: a cable may carry power, sound or both, depending on what the socket and system support. Call handling is a third matter.
