Comfort and Convenience
Preferred cabin temperature is rarely agreed on. Body size, clothing and whether someone has just walked in from the cold all shift the number that feels right, which is why the climate controls get touched so often.
Safety and Driver Assistance
A few minutes spent stationary is time well used: finding the hazard switch, the demister and the headlight control before setting off means they are not being located for the first time while traffic is moving.
Multimedia and Connectivity
Keeping a phone charged over a long drive is a separate matter from playing music or taking calls through the car. Where a charging point is provided, the useful part is simply knowing where the cable lives.
