Comfort and Convenience
Preferred seating position is a good example. Some drivers like sitting high with a clear view over the bonnet, while others prefer a lower, more reclined posture, and that split comes down to height, habit and what feels natural.
Safety and Driver Assistance
Setting mirrors, seat and lights before pulling away is simply preparation: it puts the basic controls where a driver expects them. Doing it stationary means the first kilometres are spent driving rather than sorting out settings.
Multimedia and Connectivity
Keeping a phone charged on longer trips is a routine need, especially when navigation runs the whole way. Whether a socket or a dedicated port is available, the practical question is simply where the cable ends up.
