Comfort and Convenience
Seating position is personal. Height, arm length and the way someone prefers to sit all shape what feels right, so two people of similar build often settle on noticeably different arrangements for the same route.
Safety and Driver Assistance
It is worth spending a few stationary minutes before a long drive locating the hazard lights, demisting and headlight controls. Working that out in a quiet car park is calmer than doing it in moving traffic.
Multimedia and Connectivity
A phone battery drains quickly when navigation runs for hours, so a charging arrangement matters on long routes. Where calls or music are also routed through the car, each depends on its own settings.
