Comfort and Convenience
On a winter school run, some people want the cabin warm, while others prefer cooler air because they are already in a coat. Those tastes are personal and shift with weather and the wait at the gates.
Safety and Driver Assistance
Before a night run to collect takeaway, checking how the headlamps, interior light and door locks work means those steps are not a puzzle in a dark car park. The value is simple familiarity with the cabin before the trip starts.
Multimedia and Connectivity
If someone wants a podcast in a recycling-centre queue, audio playback, if available, lets the wait pass without holding the phone. That listening need is separate from calls or charging.
