Comfort and Convenience
Preferred cabin temperature is a good example: some travellers settle at a cooler setting, while others feel chilled by it. Height, clothing and simply sitting still for hours all shift where a person feels comfortable.
Safety and Driver Assistance
Spending a few minutes with wipers, lights and mirrors while parked means fewer unfamiliar reaches later. Controls vary between cars, and a long drive is an awkward moment to start hunting for one.
Multimedia and Connectivity
Keeping a phone charged matters most when it doubles as the navigation screen, since screen-on use drains a battery steadily. Whatever charging arrangement a car offers, carrying the right cable is worth checking beforehand.
