Comfort and Convenience
Preferred cabin temperature is a good example: some travellers want steady warmth, others cooler air moving constantly. Body size, clothing and where someone sits all shift the answer, so agreeing a setting early avoids repeated adjustment.
Safety and Driver Assistance
Before setting off, it is worth locating wipers, lights, the hazard switch and mirror adjusters while stationary. Hunting for an unfamiliar stalk mid-journey turns a simple task into a distraction that is easily avoided beforehand.
Multimedia and Connectivity
Keeping a phone charged matters most when it carries navigation, since a screen in constant use drains quickly. If a suitable power outlet or cable is available, plugging in at the start beats rationing battery later.
