Comfort and Convenience
Cabin temperature is a common point of negotiation, because people differ in build, clothing and how warm they feel while sitting still. Agreeing on a setting early usually spares everyone repeated adjustments during the journey.
Safety and Driver Assistance
It helps to locate the basic controls, such as lights, wipers, mirrors and demisting, before setting off rather than mid-journey. With passengers aboard and conversation underway, a moment of preparation keeps attention where the driver wants it.
Multimedia and Connectivity
Phone charging, calls and music are separate needs, and passengers often want all three. Where charging points are available, one that a rear occupant can reach matters as much as the driver's own.
