Comfort and Convenience
Cabin temperature is a preference people rarely agree on. One passenger wants steady warmth, another prefers cooler air on the face, and the same setting feels different depending on clothing and time of day.
Safety and Driver Assistance
Anyone driving an unfamiliar car benefits from a short pause before moving off: mirrors adjusted, seat set, indicator and wiper stalks identified. Preparation done while stationary need not be worked out later in moving traffic.
Multimedia and Connectivity
Taking a call on the move is a distinct task from streaming music or topping up a battery. If hands-free functions are available, the practical gain is that a conversation needs no handling of the phone.
