Comfort and Convenience
Cabin temperature is the classic point of disagreement: what one occupant finds pleasant another finds stuffy or chilly. Preferences differ with clothing, position in the car and simply how warm a person tends to run.
Safety and Driver Assistance
Time spent before setting off on mirrors, seat position, demister and hazard lights costs little and removes the need to work things out later. Doing this while stationary keeps unfamiliar equipment from becoming a distraction mid-journey.
Multimedia and Connectivity
Battery level shapes a long trip more than people expect, since navigation drains a phone quickly. If a charging point is available, passengers can keep their own devices topped up rather than negotiating over a single cable.
