Comfort and Convenience
Airflow preference divides people: some want air aimed at the face, others find that unpleasant and prefer it directed low or at the windscreen. Sensitivity to moving air simply varies from person to person.
Safety and Driver Assistance
After a break from driving a particular car, a quick check of the indicator stalk, hazard switch and horn position is worth the pause. Preparation like this belongs in the driveway, not mid-manoeuvre.
Multimedia and Connectivity
Hands-free calling matters most to people who take work calls on the move, and it depends on whatever connection method is available. Music playback and battery charging are separate questions, each answered differently.
