Comfort and Convenience
Seating position is a common starting point. Height, arm length and how upright someone likes to sit all differ, so a position that feels natural to one person rarely feels natural to the next.
Safety and Driver Assistance
Spending a few minutes with lights, wipers, mirrors and the hazard switch while parked is simple preparation. Knowing where they sit beforehand means the first rainy evening is not when you start looking.
Multimedia and Connectivity
Charging tends to be the need that appears most often, since a phone used for navigation drains quickly. Where charging is available, it shapes longer trips more than the calling or listening functions do.
