Comfort and Convenience
Cabin temperature is a good example of how preferences diverge: what one occupant finds pleasant, another finds too warm or too cool. Differences in build, clothing and where a person sits all play a part.
Safety and Driver Assistance
Time spent stationary before departure is well used: mirrors set, seat position settled, and the location of hazard lights, wipers and demisting learned. Unfamiliar switchgear is easier to sort out in a parking space than in traffic.
Multimedia and Connectivity
A phone used for navigation across a full day drains its battery steadily, so travellers often plan how it will be topped up en route. Where charging is available on board, that concern largely disappears.
