Comfort and Convenience
Cabin temperature is a common point of disagreement: people differ in how warm they like to be, depending on clothing, activity and personal sensitivity. Agreeing on a setting early saves repeated adjustments during the journey.
Safety and Driver Assistance
Locating lights, wipers, mirrors and hazard switches before setting off means you are not searching for them while moving. A few unhurried minutes parked make the first part of an unfamiliar route calmer.
Multimedia and Connectivity
Passengers often arrive with low batteries, so knowing where power is available and who gets it avoids negotiation mid-route. If a charging point is present, a cable that suits each phone matters as much.
