Comfort and Convenience
People rarely agree on cabin temperature. A setting that suits the driver can feel cool to someone sitting behind, because clothing, sun through the side glass and airflow direction differ by seat.
Safety and Driver Assistance
Mirrors and seat position are worth setting before moving off rather than at the first junction. Adjusting them while stationary also makes an unfamiliar car feel predictable sooner.
Multimedia and Connectivity
Taking a call is a different task from playing music: a call depends on a microphone and clear speech, while audio mainly needs a steady source. Where hands-free functions exist, they keep the phone down.
