Comfort and Convenience
Preferred cabin temperature varies widely from one traveller to the next, shaped by clothing, where someone sits relative to the sun and simple personal habit. Agreeing a setting early tends to save repeated debate en route.
Safety and Driver Assistance
A few minutes stationary is enough to locate hazard lights, demisting and the headlight switch. Doing this before departure means the first time you need them is not also the first time you look.
Multimedia and Connectivity
Navigation apps drain a phone quickly, so a long day usually calls for keeping it powered. If a suitable charging point is available on board, a cable of the right type still has to travel with you.
