Comfort and Convenience
Cabin temperature is a good example of a preference nobody agrees on. One passenger wants air moving constantly, another finds a draught unpleasant, and the same setting can feel right in the morning and wrong by afternoon.
Safety and Driver Assistance
A few minutes spent stationary getting used to unfamiliar switchgear, mirror settings and instrument layout is time that does not have to be found mid-traffic. Preparation of this kind costs little.
Multimedia and Connectivity
Taking a call on the move is mainly a question of where the phone sits and whether audio can be routed through the car. Music playback and battery charging are separate matters entirely.
