Comfort and Convenience
Cabin temperature is a good example: some travellers want steady warmth, others prefer cooler air moving past them. Height, clothing and where someone sits all shift the answer, so longer trips usually involve negotiation rather than one setting.
Safety and Driver Assistance
Before setting off, it helps to locate the wipers, lights, demisters and hazard switch while parked. Learning them calmly costs a minute, whereas hunting for an unfamiliar stalk in heavy rain competes with watching the road.
Multimedia and Connectivity
Phone battery is the usual concern, since navigation drains it fastest. If a charging outlet is available, a cable that matches the handset matters more than the socket itself; charging keeps the screen alive, nothing else.
