Comfort and Convenience
Cabin temperature is a common comfort choice: one person may want cooler air on a sunny errand, while another prefers more warmth on the same route.
Safety and Driver Assistance
Before a night trip, it helps to locate the light switch and indicator stalk while the car is still parked, so those actions are already known once the journey starts.
Multimedia and Connectivity
On a long wait in traffic, someone may want a podcast playing. That need is about starting audio clearly, if a player is available, and it is not the same as charging a handset or answering a call.
