Comfort and Convenience
Cabin temperature is where preferences diverge sharply: one person wants steady warm air, another fresh air from an open window. Clothing, the time of year and how long the drive lasts all feed into it.
Safety and Driver Assistance
Mirrors, seat and steering position are worth setting before the wheels move rather than at the first junction. The habit matters most in an unfamiliar or newly bought car, where nothing is yet automatic.
Multimedia and Connectivity
Calls are the everyday case: someone ringing back mid-errand. Where hands-free calling is available, it keeps the conversation going without a phone in hand; otherwise the sensible answer is simply pulling over first.
