Comfort and Convenience
Cabin temperature is a good example: some travellers prefer a cool, airy setting, others warmth. Preferences differ with clothing, metabolism and seating position, so agreeing a compromise early avoids constant adjustment on the road.
Safety and Driver Assistance
Before setting off, it is worth locating wipers, lights, demisting and hazard switches while parked. Searching for an unfamiliar control in traffic or bad weather takes attention away from the road.
Multimedia and Connectivity
Phone battery is the usual pressure point on a long drive. If a charging option is available, keeping the handset topped up matters separately from whether calls or music are routed through the car.
