Comfort and Convenience
Cabin temperature divides people more than almost anything else: some want fresh air moving constantly, others feel a draught at once. Clothing, habit and trip length all push the setting differently.
Safety and Driver Assistance
Sitting in a car that is new to you, a minute spent identifying the gear selector, parking brake and demist control is time well spent. Doing it parked means fewer unfamiliar movements later.
Multimedia and Connectivity
Calls are a need of their own, separate from music or charging: someone speaking in traffic wants to be heard against road noise. Where hands-free telephony is available, clarity depends on microphone placement.
