Comfort and Convenience
Cabin temperature is a personal setting rather than a correct number. Someone arriving from a cold car park and a passenger in a heavy coat rarely want the same thing, so agreement is usually a small negotiation.
Safety and Driver Assistance
It is worth finding the hazard lights, demister and horn while parked. Searching for a basic function in moving traffic is a distraction, and a minute spent beforehand removes that hunt later.
Multimedia and Connectivity
Battery level is the everyday concern: a phone used for navigation drains steadily, so where a charging option exists, keeping the cable to hand matters more than which socket or standard it uses.
