Comfort and Convenience
Preferred cabin temperature varies widely, and some people sit comfortably a few degrees cooler than others. Where passengers share one setting, the result is usually a compromise between what each would choose alone.
Safety and Driver Assistance
Finding the wiper, light and hazard switches while parked means less searching later, when attention belongs on the road. A few minutes in an unfamiliar cabin covers most controls used in traffic.
Multimedia and Connectivity
A phone running low on a long drive needs power rather than data, so a charging point matters separately from whatever handles calls or plays audio.
