Comfort and Convenience
Seating preferences differ because bodies and habits do. Height, leg length and how close someone likes to sit to the wheel all vary, so a position one driver finds natural can feel wrong to the next.
Safety and Driver Assistance
Time spent learning where the basics sit, such as lights, wipers, hazards and mirror adjustment, is time not spent hunting for them mid-journey. That kind of preparation is simplest while the car is still parked.
Multimedia and Connectivity
Phone battery is the usual errand worry, since a route app drains it across a morning of short hops. Where a charging option is available, using it keeps the phone ready for calls later; music is a separate matter.
