Comfort and Convenience
Seating position is a personal preference: some drivers sit upright and close to the wheel, others further back with arms extended.
Safety and Driver Assistance
Locating the wipers, lights, mirror adjusters and hazard switch before setting off means not searching for them later. A short pause while still parked turns unfamiliar controls into movements that can be made without looking down.
Multimedia and Connectivity
Keeping a phone charged on a long drive is a separate matter from taking calls or playing music, since each may rely on a different socket or connection. Knowing which does what avoids fumbling mid-journey.
