Comfort and Convenience
Preferred cabin temperature is a good example: people settle at different levels, so one setting can suit one occupant and feel wrong to the next. Talking it through early makes shared journeys simpler.
Safety and Driver Assistance
Before setting off somewhere unfamiliar, it is worth spending a few quiet minutes locating the basic controls — lights, wipers, demisting. Preparation of that kind belongs on the driveway rather than mid-journey.
Multimedia and Connectivity
Keeping a phone charged through a long day is a need in itself, distinct from calls or music. Where charging is available on board, it counts most when mapping runs continuously and the battery drains steadily.
