Comfort and Convenience
Preferred cabin temperature is a clear example. Some people settle a few degrees cooler than others, and clothing, the time of day and where someone sits all change what feels right at the same setting.
Safety and Driver Assistance
Taking a moment before setting off to locate the hazard lights, wipers and demisters is simple preparation. Working them out while stationary leaves fewer things to puzzle over later, especially in a car driven only occasionally.
Multimedia and Connectivity
Keeping a phone charged matters on longer trips if you depend on it after arriving. Where a suitable power source is provided, topping up during the drive is easier than hunting for one at the destination.
