Comfort and Convenience
Cabin temperature is a good example, because one person sets it warm while another wants cool air on the face. Preferences shift with clothing, with how long the journey is, and simply with habit.
Safety and Driver Assistance
A few minutes spent stationary on lights, wipers, mirrors and the hazard switch is time well used before setting off. Sorting these while parked leaves fewer decisions for later, when the road is already asking for attention.
Multimedia and Connectivity
Battery level is the everyday concern, since a phone used for navigation drains quickly, so where a charging point is available on board, an errand run doubles as a top-up. Calls and music remain separate questions.
