Comfort and Convenience
Preferred cabin temperature differs from person to person, and the same setting can feel warm to one passenger and cool to another. Clothing, time of day and individual tolerance explain much of that gap.
Safety and Driver Assistance
An unfamiliar car rewards a short pause in the driveway: adjust mirrors, find the hazard switch, note where the parking brake sits. Doing this while parked removes the need to work it out later.
Multimedia and Connectivity
Hands-free calling matters most to drivers who take work calls on the move, since it keeps the phone out of the hands. Music playback and charging remain separate questions from that one.
