Comfort and Convenience
On a winter morning commute, some people like a warmer cabin while others prefer a cooler one, because temperature comfort differs from person to person.
Safety and Driver Assistance
Time spent with basic switches before an evening appointment means those controls are already known, so that step sits with packing and route checks rather than later searching.
Multimedia and Connectivity
During a long wait at school pickup, keeping a phone charged is a practical need, and a cabin socket, if present, can support that without involving calls or music.
