Comfort and Convenience
Preferred cabin temperature differs from person to person, and passengers often disagree with the driver. Clothing, time of day and simply how warm someone tends to run all feed into that choice.
Safety and Driver Assistance
A few minutes before setting off — adjusting the mirrors, locating the hazard switch, checking what each stalk does — means those actions are already familiar rather than worked out mid-journey.
Multimedia and Connectivity
Where hands-free calling is available, it depends on clear speech in both directions, a different requirement from music playback. Charging is separate again: a cable carrying power may not carry audio.
