Comfort and Convenience
Cabin temperature is a matter of taste rather than a fixed setting. Passengers arrive from different starting points, in clothing and seating position, so agreeing a compromise early avoids quiet disagreement later.
Safety and Driver Assistance
A few minutes spent stationary before setting off is worth more than guesswork at speed. Locating hazard lights, demisting and headlight settings while parked means an unfamiliar cabin feels known by the first junction.
Multimedia and Connectivity
Phone battery is the quiet constraint on a long drive, since navigation drains it steadily. If a charging option is available on board, using it from the start keeps the map running without rationing screen time.
