Comfort and Convenience
People differ on cabin temperature during short errands: one passenger may want cooler air after a sunny walk from the shops, while another prefers a milder setting for a child in the back.
Safety and Driver Assistance
Taking a quiet minute before a weekend market trip to find the indicator, horn and light switches makes those actions available from memory once the car is moving. That rehearsal is simply preparation, not a substitute for paying attention.
Multimedia and Connectivity
A common phone need is taking a brief call from a courier while parked outside a pickup point. If a hands-free function is present, the conversation can stay in the cabin; otherwise the handset is used after the car is stopped.
