Comfort and Convenience
Cabin temperature is a common point of negotiation, because people arrive dressed differently and sit in different places relative to vents and glass. Agreeing on a setting early usually spares everyone repeated adjustments later.
Safety and Driver Assistance
Spending a moment with wipers, lights and mirrors before setting off means fewer distractions once passengers are aboard and conversation is under way. Preparation while stationary is simply easier than searching for something mid-journey.
Multimedia and Connectivity
Long trips drain phone batteries, so knowing where a charging point sits, if one is available, matters more than the connection method. Calls and music are separate needs and may be handled differently.
