Comfort and Convenience
Seating position is a personal preference. Height, reach and preferred posture differ from one driver to the next, so an arrangement that suits one person can feel wrong to another who shares the same car.
Safety and Driver Assistance
Time spent before setting off is well used in locating the lights, wipers, mirrors and hazard switch. Working these out while stationary means one less thing to puzzle over later, when the road is asking for attention.
Multimedia and Connectivity
Keeping a phone charged through a long day out is a practical concern in its own right, separate from calls or music. Where a charging option exists, it helps if the phone rests somewhere secure while connected.
