Comfort and Convenience
Seating preferences vary a great deal, since height, leg length and preferred posture differ from person to person. A position that suits one driver can feel awkward to the next.
Safety and Driver Assistance
Knowing where the lights, wipers and hazard switch sit before moving off saves searching for them later. Preparation of that kind is about familiarity rather than any particular equipment.
Multimedia and Connectivity
Phone batteries drain over a long drive, so somewhere to charge is useful. Where hands-free calling is available it keeps conversations simple, and music remains a separate matter of preference.
