Comfort and Convenience
Cabin temperature is a good example of a preference with no single right answer: build, clothing and habit all influence what feels pleasant, so two people in the same car often want different settings on the same morning.
Safety and Driver Assistance
Before setting off, especially in an unfamiliar car, it is worth locating the essentials: lights, wipers, demister and hazard switch. Doing that while stationary means one less thing to work out once traffic is moving.
Multimedia and Connectivity
Battery level matters on longer days, and a charging point in the cabin is what keeps a phone usable at the far end of a journey, a separate question from how calls are handled or how music reaches the speakers.
