Comfort and Convenience
Cabin temperature is a good example. Some people travel best with cool air moving steadily, others prefer warmth and little draught, and height and clothing change the answer again, so one setting rarely suits everyone aboard.
Safety and Driver Assistance
Spending a few minutes with lights, wipers, mirrors and the hazard switch before setting off is sensible preparation. Learning where things sit while parked is easier than working it out once traffic is moving.
Multimedia and Connectivity
Keeping a phone charged on the move matters most when it is also the navigation screen. If a charging option is available, a stable place to rest the phone is worth just as much.
