Comfort and Convenience
Cabin temperature is the classic point of disagreement, as the same air feels pleasant to one person and chilly to another. Clothing, seating position and how directly the vents blow all differ from seat to seat.
Safety and Driver Assistance
A minute spent before setting off, locating the wipers, lights, mirrors and hazard switch, means those things are already known when they are needed, rather than being searched for while the road and the conversation both demand attention.
Multimedia and Connectivity
Phone battery is an ordinary concern on longer trips, since navigation and screen time drain it quickly. Where a charging point is provided and can be reached from the seats, a device can be topped up en route.
