Comfort and Convenience
Cabin temperature is a good example of preference. What feels pleasant depends on clothing, the time of day and plain habit, so two people sharing the same short trip often want different settings.
Safety and Driver Assistance
Before setting off, it is worth locating the basics: lights, wipers, mirrors, demisting. Sorting that out while stationary means the first busy junction is not also the moment a driver learns where a switch lives.
Multimedia and Connectivity
Phone battery is the everyday concern, since a day of navigation drains it. Where charging is available in a car, it keeps the handset usable after arrival, which is a separate matter from calls or music.
