Comfort and Convenience
Cabin temperature is a good example: some people prefer a cool draught of air, others dislike anything blowing directly on them. Preferences here follow habit and clothing as much as the weather outside.
Safety and Driver Assistance
Spending a few minutes with lights, wipers and mirrors while parked means fewer unknowns once the journey begins. Settling seating and mirror positions before setting off is part of the same unhurried preparation.
Multimedia and Connectivity
Keeping a phone charged on longer journeys is an ordinary concern, and where charging is available it also decides where the phone rests. If music matters on long drives, that is a separate question from hands-free calling.
