Comfort and Convenience
Cabin temperature divides travellers more than almost anything else: one person wants warm air, another prefers it cool and moving. Agreeing on a setting early is easier than adjusting it repeatedly over hours.
Safety and Driver Assistance
Familiarity with the gear selector, parking brake and hazard switch is worth building in a quiet car park rather than on the road. Preparation of this kind costs a few minutes at most.
Multimedia and Connectivity
Calls on a long drive are best handled without holding a phone, so whatever hands-free method is available should be set up before departure. Audio playback and charging are separate matters, each with its own arrangement.
