Comfort and Convenience
Seating position is a personal matter. Some people prefer to sit high for a clear view of the road ahead, others lower and more enclosed, and height, build and driving habits all push that preference in different directions.
Safety and Driver Assistance
Time spent before setting off is rarely wasted. Knowing where the lights, wipers, mirrors and hazard switch are means those things can be found without hunting for them later, particularly on an unfamiliar or borrowed car.
Multimedia and Connectivity
Keeping a phone charged during the day is its own need, separate from calls or music. If a suitable power outlet or cable is available, a long drive ends with a usable battery rather than a flat one.
