Comfort and Convenience
Comfort preferences are personal because bodies and routines differ. Seating height that suits one driver feels wrong to another, and a cabin temperature that one passenger finds pleasant may be a degree too warm for someone else.
Safety and Driver Assistance
Learning where the basic controls sit is best done while parked. Sorting out mirrors, seat position and demisting before setting off means those adjustments are not competing for attention once the journey is under way.
Multimedia and Connectivity
Arriving with a nearly flat phone is a common commuting annoyance, so if a charging point is available it is worth using it for that alone, separately from whatever handles calls or music.
