Comfort and Convenience
Cabin temperature is a good example: some travellers want steady warmth, others prefer cooler air moving around them. Preferences differ with clothing, metabolism and where someone sits, so agreeing a setting early keeps a long trip civil.
Safety and Driver Assistance
Before setting off, it is worth locating the wiper, lighting and demisting controls while parked. Hunting for an unfamiliar switch in rain or fading light turns a simple adjustment into a distraction.
Multimedia and Connectivity
Keeping a phone charged is its own need, separate from calls or music. If a suitable socket or cable is available, planning where the phone sits and stays powered avoids rummaging mid-journey.
