Comfort and Convenience
Cabin temperature is a good example: some travellers settle at a cooler setting, others feel a draught immediately. Height, clothing and where someone sits all change what feels right on the same journey.
Safety and Driver Assistance
Learning where the essentials sit while parked costs a minute and saves fumbling later. Hazard lights, demisting and the horn are all things drivers reach for suddenly, rarely at a convenient moment.
Multimedia and Connectivity
A phone used for navigation drains steadily, so a way to keep it powered matters more than on short trips. If charging is available on board, a suitable cable belongs in the luggage.
