Comfort and Convenience
Tolerance of noise varies widely. One person happily talks over road and wind sound for hours, while another prefers quiet and keeps conversation short, so the same cabin can suit two people differently.
Safety and Driver Assistance
Preparation is easier stationary than in traffic. Setting mirrors and seat, then trying the indicator stalk, headlight modes and any on-screen menus while parked, means fewer unfamiliar movements once the road demands attention.
Multimedia and Connectivity
Passengers rarely agree on listening, so an agreed playlist or downloaded episodes saves fiddling at speed. If the car supports pairing more than one device, music and a passenger's calls need not share the same phone.
