Comfort and Convenience
Cabin temperature is a good example of a personal preference: the setting one occupant finds pleasant can feel cool or stuffy to someone beside them, so longer trips often involve quiet negotiation.
Safety and Driver Assistance
Learning where the lights, wipers and hazard switch sit while stationary means fewer glances away from the road later. Preparation of this kind is simply about removing avoidable hesitation in an unfamiliar cabin.
Multimedia and Connectivity
Battery life is a common concern on a long drive, since navigation drains a phone quickly. If a charging option is available, knowing which cable or socket it needs saves searching at the first stop.
