Comfort and Convenience
Cabin temperature is rarely agreed on. What one occupant calls pleasantly warm another finds stuffy, since clothing, metabolism and where someone sits relative to the vents all pull the preference in different directions.
Safety and Driver Assistance
Adjusting the seat and mirrors, then locating the hazard switch, belongs before the journey rather than during it. Preparation while parked means fewer decisions competing for attention once traffic sets the pace.
Multimedia and Connectivity
Listening habits differ: radio, stored music and streaming draw on separate sources. If a call arrives, playback usually pauses, while charging is a separate matter again — a powered socket implies nothing about audio.
