Comfort and Convenience
Preferred cabin temperature varies because people feel warmth and airflow differently, so a setting one person finds pleasant may feel too cold or stuffy for another.
Safety and Driver Assistance
Practicing where wiper, lighting, and defroster controls are located helps reduce last-minute searching, letting a driver keep attention on the road and surroundings.
Multimedia and Connectivity
Passengers often want to keep a phone charged during a long trip, and if a USB port is available, it can support that need without interfering with other audio choices.
