Comfort and Convenience
People differ on how much moving air they want across their face. One traveller may like a gentle breeze, while another prefers still air so papers and clothing stay put.
Safety and Driver Assistance
Taking a minute in a quiet car park to locate the horn, indicators, and headlamp switch makes those actions easier to repeat later, when traffic or weather may demand quicker use.
Multimedia and Connectivity
Someone may want their own playlist during a quiet afternoon drive. If the system can play from a phone, that list can run without swapping discs or radio stations at every pause.
