Comfort and Convenience
Preferred cabin temperature is a good example: some people travel comfortably in cool air while others want warmth, and passengers seated further back often feel conditions differently from whoever is driving.
Safety and Driver Assistance
Spending a few minutes before setting off to locate lights, wipers and hazard switches is simple preparation. Doing it while parked means the first unfamiliar moment does not arrive halfway through a journey.
Multimedia and Connectivity
Keeping a phone charged over a long day out is a common need, and where any available power outlet sits determines whether a cable reaches the driver or the rear seats comfortably.
