Comfort and Convenience
Seating preferences differ because bodies differ: leg length, torso height and shoulder width all change where a comfortable driving position sits. What one person calls upright, another finds cramped, so the same settings rarely suit two drivers.
Safety and Driver Assistance
Learning where the wipers, lights and demister controls sit while parked means you are not searching for them later. Preparation of this kind lets attention stay with driving rather than the dashboard.
Multimedia and Connectivity
Keeping a phone charged during a long drive is a separate matter from playing music or taking calls through the car. If a socket or wireless pad is available, charging can continue while audio plays.
