Comfort and Convenience
Cabin temperature is a classic point of disagreement. One passenger wants airflow on the face, another finds the same setting chilly, and people arriving in coats often need different conditions from those already settled.
Safety and Driver Assistance
Time spent reading the owner's handbook before setting off turns unfamiliar symbols and menu layouts into known quantities. Preparation of this kind belongs at the kerb, not halfway across a busy junction.
Multimedia and Connectivity
Calls arriving mid-journey raise a practical question of how they are answered. Where hands-free operation is available it keeps the conversation off the handset; music playback and charging are handled separately.
