Comfort and Convenience
Cabin temperature is a good example: some people want air moving constantly, others find a draught unpleasant and prefer gentler settings. Height, clothing and time of year all change what feels right on a given day.
Safety and Driver Assistance
A few minutes stationary is enough to locate wipers, lights and demisting before setting off. Doing this while parked means those functions are already known when weather or light changes during the drive.
Multimedia and Connectivity
Keeping a phone charged on a long day matters in its own right, separately from calls or music. If a charging option is available in the cabin, the useful question is whether it reaches where the phone actually sits.
