Comfort and Convenience
Seating position is a clear example. Taller occupants often want more distance from the pedals, while shorter drivers tend to prioritise a clear view over the bonnet, so one setting rarely suits two people equally.
Safety and Driver Assistance
Learning where the basic controls sit before setting off is simply sensible preparation. Mirrors, lights and demisting are easier to sort out while parked than while approaching an unfamiliar junction in poor weather.
Multimedia and Connectivity
Keeping a phone charged on a long drive is a separate question from playing music or handling calls. Where a power outlet is provided, it is worth knowing in advance which cable it expects.
