Comfort and Convenience
Cabin temperature is a good example: the setting one person finds pleasant leaves another reaching for a jacket. Height, clothing and where the airflow lands all play a part, which is why preferences rarely match.
Safety and Driver Assistance
Sorting out mirrors, seat position and the lighting switches before setting off takes a minute in a car park and avoids doing it at speed. Unfamiliar hire or newly bought cars especially reward that pause.
Multimedia and Connectivity
Phone charging is the practical one on a long drive, since navigation drains a battery faster than anything else. Where a suitable socket or cable is available, the screen stays alive for the whole route.
