Comfort and Convenience
Cabin temperature is the preference people disagree about most, because perceived warmth depends on clothing, seating position and how directly air reaches someone. Agreeing a setting before departure avoids repeated adjustments later.
Safety and Driver Assistance
Knowing where the essential controls sit, such as lights, wipers, the hazard switch and demisting, means a driver can operate them without searching mid-journey. A few minutes stationary is the easiest time to locate them.
Multimedia and Connectivity
Passengers often arrive with low batteries, so where a phone can be charged matters more than how many ports exist. If charging is available, keeping it separate from music duties avoids one device serving everything.
