Comfort and Convenience
Cabin temperature is the usual point of disagreement: one person wants air moving, another finds the same setting chilly. Clothing, build and where somebody is sitting all change how warm a given setting feels.
Safety and Driver Assistance
It is worth a moment before setting off to locate lights, wipers, demisters and the hazard switch. Learning where they sit while stationary means less searching later, when weather or traffic changes without warning.
Multimedia and Connectivity
Phone batteries drain fastest when navigation runs the whole way, so a charging point earns its place on longer trips. Where hands-free calling is offered, it keeps a conversation apart from whatever music passengers have chosen.
