Comfort and Convenience
Seating comfort is personal: height, leg length and posture differ, so a position that suits one driver feels wrong to the next. That is why two people sharing a car rarely settle on the same setup.
Safety and Driver Assistance
Finding the basic controls before setting off is simple preparation: lights, wipers, demister, hazard switch. Searching for any of them for the first time in moving traffic turns a small task into a distraction.
Multimedia and Connectivity
Charging a phone is a separate need from taking calls or playing music, even when the same connection can serve more than one of them. Before a long drive, it helps to know which of those functions are available.
