Comfort and Convenience
Cabin temperature is the classic disagreement: what one person finds pleasant, another finds stuffy or cold. Tolerance varies with clothing, where someone sits relative to the sun, and simply how warm they run.
Safety and Driver Assistance
A few quiet minutes before setting off are worth taking: finding the lights, wipers, demister and hazard switch while parked means less searching later. That is easier done calmly than with passengers waiting and traffic moving.
Multimedia and Connectivity
Batteries drain fastest on the days navigation runs for hours. If a charging point is available and reachable from where a passenger sits, a phone can top up en route rather than arriving flat.
