Comfort and Convenience
Drivers differ in how upright they like to sit: some prefer a low position for a sense of enclosure, others sit higher for a clearer view over the bonnet. Body proportions explain much of this.
Safety and Driver Assistance
Locating wipers, lights and demisting before setting off means you are not searching for them later. A few minutes stationary is easier than learning an unfamiliar layout in moving traffic.
Multimedia and Connectivity
Charging and audio are separate needs: a cable may power a phone without carrying sound, while wireless audio leaves the battery draining. Knowing which socket does what helps on long journeys.
