Comfort and Convenience
How much airflow people want on a hot afternoon shop run differs, because one person may like a stronger breeze while another finds the same setting uncomfortable.
Safety and Driver Assistance
Checking where the lights, indicators and hazard switch sit before a foggy morning commute is useful preparation, so those actions are already known when visibility drops.
Multimedia and Connectivity
If a brief work call is needed on the way to an appointment, being able to speak without holding the handset is the practical point, where that function is available.
