Comfort and Convenience
People rarely agree on cabin temperature. Passengers who feel the cold often want warmer air than the driver, so those sharing a car usually settle on a compromise setting.
Safety and Driver Assistance
Adjusting the mirrors and seat while stationary is easier than attempting it in moving traffic. The same applies to any car driven rarely, where the switch layout may still be unfamiliar.
Multimedia and Connectivity
Taking a call while driving is a different task from choosing music. Hands-free calling, where supported, routes the conversation through the car rather than a handset held in one hand.
