Comfort and Convenience
Preferred seating position varies widely between drivers: some want a high, commanding view forward, others sit low and further back. The same cabin can therefore feel quite different to two people of similar height.
Safety and Driver Assistance
A few minutes spent in a parked car locating lights, wipers and the demister saves hunting for them later, when attention belongs on the road. Preparation of that kind is simply routine familiarity.
Multimedia and Connectivity
A phone tends to run low on power by the end of a long drive, so a reachable charging point is useful. Where calls are supported, they interrupt listening, and music arrangements differ again.
