Comfort and Convenience
Preferred cabin temperature is a good example: some people are content a couple of degrees cooler than others, because clothing, activity before setting off and personal sensitivity all differ, so occupants usually negotiate a middle setting.
Safety and Driver Assistance
Spending a few minutes with wipers, lights and mirrors before moving means you are not searching for them later. Preparation of this kind keeps attention where it belongs, on the road ahead.
Multimedia and Connectivity
Keeping a phone charged through a long day matters because navigation drains a battery quickly. Where a charging option is available, a settled place to rest the handset makes that habit easier to keep.
