Comfort and Convenience
People differ on cabin airflow because a warm school run can feel stuffy to one passenger, while another wants still air so papers and light clothing stay put.
Safety and Driver Assistance
Before a foggy dawn start, locating the demister and light switches while still parked means those actions are already known when the car is rolling.
Multimedia and Connectivity
During a wait at the station, charging a phone is a power task if a socket is fitted. Playing a podcast is a separate listening choice from taking a call.
