Comfort and Convenience
Cabin temperature is a common point of disagreement: what feels pleasant to one person can seem too warm or too draughty to another. Preferences differ with clothing, seating position and simple habit, so travellers often negotiate.
Safety and Driver Assistance
Spending a minute with the main controls before setting off, such as lights, wipers, mirrors and demisting, means less improvising later. Preparation is easier while parked than in traffic, particularly in an unfamiliar car with people waiting.
Multimedia and Connectivity
Passengers often arrive with low batteries, so a way to charge en route matters on longer trips. Where charging is available it need not also carry audio, and hands-free calling is a separate function again.
