Comfort and Convenience
Comfort preferences vary because bodies do. Height, leg length and back shape all change where someone wants to sit, so two people in the same car often settle on quite different positions before setting off.
Safety and Driver Assistance
A few minutes spent locating the essentials before pulling away is time well used, particularly in a car you drive rarely. Hazard lights, demisting and headlight settings are the sort of things worth finding while stationary.
Multimedia and Connectivity
Phone battery is the everyday concern, since navigation drains it quickly and a way to keep the handset charged en route matters. Whether calls route through the car, and how music is selected, depends on what the system supports.
