Comfort and Convenience
Preferred cabin temperature is a good example: some travellers settle at a cooler setting, others feel a draught quickly. Build, clothing and where someone sits all shape the choice, so agreement usually comes through small adjustments.
Safety and Driver Assistance
Learning where the lights, wipers and demisting controls sit is worth a few unhurried minutes in the driveway. Rain or dusk rarely arrives conveniently, and preparation means less searching when attention belongs on the road.
Multimedia and Connectivity
Keeping a phone charged matters most on a long run, since navigation drains a battery steadily. If a suitable socket or cable is available, it is worth locating it before departure rather than mid-route.
