Comfort and Convenience
Cabin temperature divides people more than almost anything else. One passenger wants airflow on their face, another finds the same setting chilly, so groups travelling together usually negotiate rather than agree.
Safety and Driver Assistance
Knowing where the hazard switch, demister and horn sit is worth a few minutes in a stationary car. Rain, tunnels or a sudden queue are poor moments to start reading labels.
Multimedia and Connectivity
Calls on the move are the awkward part. Where hands-free answering is available the phone can stay put; where it is not, the practical answer is returning the call at a stop.
