Comfort and Convenience
Cabin temperature is a common point of disagreement: what one person finds pleasant, another finds stuffy or chilly. Preferences shift with clothing, with where someone is sitting relative to the sun, and with simple individual difference.
Safety and Driver Assistance
Spending a couple of minutes with the wipers, lights, mirrors and hazard switch before setting off is worthwhile, particularly in a car you drive rarely. Preparation leaves one less thing to work out once traffic demands attention.
Multimedia and Connectivity
Phone battery becomes a practical concern on longer trips, because passengers often navigate or look things up along the way. Where a charging point is available, agreeing who uses it avoids the usual last-minute scramble.
