Comfort and Convenience
Some passengers like a window slightly open for fresh air on a long afternoon, while others find the draught unpleasant, so the group often has to agree a compromise.
Safety and Driver Assistance
A few minutes with the handbook the night before a trip can show where the hazard switch and fuel-filler release sit, so those actions do not have to be learned on a busy forecourt.
Multimedia and Connectivity
If the phone can be used on speaker, a brief call to confirm a booked table can be made during a pause, with music off so the voices stay distinct.
