Comfort and Convenience
How upright a driver likes to sit varies widely; some prefer a high, close posture for visibility in town, others a laid-back stance. Height, habit and the length of a typical trip explain much of the difference.
Safety and Driver Assistance
Unfamiliar controls are hardest to find in rain or darkness, exactly when they are wanted. Learning the demister, headlight and wiper positions before setting off turns a fumbled search into an automatic movement.
Multimedia and Connectivity
Calls on the move are the common case: answering without handling the phone keeps hands where they belong. Whatever pairing method a car offers, it is worth setting up while parked, separately from charging or audio.
