Comfort and Convenience
Preferred cabin temperature is a clear example: some people want steady warmth, others cooler air. Body build, clothing and the climate someone is used to all shape what feels pleasant on the same journey.
Safety and Driver Assistance
Knowing where the wipers, lights and demisting are before setting off means a driver is not hunting for them later. Preparation of this kind is about orientation, not about any particular equipment being present.
Multimedia and Connectivity
Keeping a phone charged across a long trip is a separate need from calling or playing music. Where a charging point exists, its position and output decide whether the battery genuinely gains ground.
