Comfort and Convenience
Preferred cabin temperature varies widely between people, and passengers sharing a car rarely agree on it. Height and build also change what counts as a natural seating position, which is why comfort is discussed individually rather than as a single standard.
Safety and Driver Assistance
Spending a few minutes with the controls before setting off is simply sensible preparation. Knowing where the hazard lights, demister and headlight switch sit means less time spent looking away from the road later.
Multimedia and Connectivity
Phone battery life is the usual constraint on a long day out, since navigation apps drain it steadily. If a charging point is available and a suitable cable is packed, that concern largely disappears before arrival.
