Comfort and Convenience
Preferred distance from the pedals and steering wheel varies widely, because body proportions and driving habits differ. Two people of similar height may still settle on different positions, which is why each driver works out their own.
Safety and Driver Assistance
Locating lights, wipers and the hazard switch while parked means less searching later, when attention belongs on the road. A few minutes spent with the handbook before an unfamiliar journey is preparation rather than guesswork.
Multimedia and Connectivity
Keeping a phone powered during a long drive is a separate matter from playing music or taking calls. If a suitable socket or port is present, a cable and a stable resting place cover the charging need.
