Comfort and Convenience
Drivers who carry bulky jackets or bags often prefer extra elbow room near the door, while those who travel light may prefer a narrower seat so their arm rests exactly where it feels natural.
Safety and Driver Assistance
Practicing the reach to the mirror adjustment and the indicator stalk when parked reduces the chance of an awkward moment when a lane change is needed later.
Multimedia and Connectivity
Listening to a spoken-word podcast while commuting requires clear sound, but simply connecting the phone and placing it in a stable spot prevents the screen from becoming a distraction at slower speeds.
