Comfort and Convenience
Cabin temperature divides people more than almost anything: one passenger wants air flowing constantly, another finds the same setting cold. Preferences shift with clothing and season too, so agreement on short trips often involves compromise.
Safety and Driver Assistance
Mirrors, seat and steering wheel are worth setting before moving rather than at the first junction. Reading how the instrument display is organised while stationary also makes any warning shown later easier to interpret.
Multimedia and Connectivity
Calls taken on the move are the usual test: a hands-free arrangement, where available, lets a conversation continue without a handset. Music and charging are separate concerns, each with its own settings and habits.
