Comfort and Convenience
Cabin temperature is a good example: some travellers prefer a cool, brisk setting, others something warmer. Preferences differ with clothing, metabolism and where a person sits, so agreeing a compromise early avoids repeated adjustment later.
Safety and Driver Assistance
Learning where the essential controls sit — lights, wipers, demisting, hazard switch — is best done while parked. Searching for them in rain or darkness draws attention away from the road for longer than it should.
Multimedia and Connectivity
Battery level matters on a long drive, because navigation apps drain a phone quickly. If a charging point is available, keeping the phone topped up is a separate question from whether calls or audio playback are supported.
