Comfort and Convenience
Preferred cabin temperature varies widely. One passenger reaches for more warmth while another finds the same setting stuffy, and clothing, time of year and how recently someone walked outside all feed into that difference.
Safety and Driver Assistance
A car that is new or borrowed deserves a few stationary minutes: adjust the mirrors, try the indicator stalk, find the hazard switch. Preparation turns unfamiliar layouts into something the hands already know.
Multimedia and Connectivity
Calls arrive mid-journey whether or not the moment suits. If hands-free calling is set up, answering need not involve holding a handset; otherwise the sensible option is returning the call once parked.
