Comfort and Convenience
A preferred seating position is personal: people differ in height, in reach, and in how upright they like to sit, so an arrangement that suits one driver will not suit the next. Preferences are worth working out individually.
Safety and Driver Assistance
A few minutes before setting off, spent identifying the controls a journey will call for, removes the need to hunt for them afterwards. Preparation of this kind is simply orientation carried out while the car is still stationary.
Multimedia and Connectivity
Keeping a phone charged on a longer trip is a need of its own, distinct from taking calls or choosing music. Where a charging option is provided, knowing its location beforehand saves rummaging once the journey has begun.
