Comfort and Convenience
Cabin temperature divides people more than almost anything else. One passenger reaches for warmth while another wants air moving, so the setting that suits everyone on board is usually a compromise.
Safety and Driver Assistance
Mirrors, seat and steering adjustment belong to the moments before a journey begins rather than during it. Setting them while parked also gives time to notice which warning lamps stay lit.
Multimedia and Connectivity
Hands-free calling answers a narrow but common need: speaking without holding the handset. Where such a function is offered, microphone placement and speaker volume matter more than the menu it sits behind.
