Comfort and Convenience
Cabin temperature divides people more than almost anything else. One passenger reaches for warmth within minutes of setting off, while the driver beside them has already opened a vent, and neither preference is wrong.
Safety and Driver Assistance
Setting mirrors and seat position before pulling away is a habit worth keeping, and the same goes for locating the hazard switch. Preparation done while stationary is preparation that does not compete with driving.
Multimedia and Connectivity
Hands-free calling is the need that surfaces most on a commute, since that is when messages arrive. If the system supports it, answering through the car's controls keeps both hands where they belong.
