Comfort and Convenience
Passengers rarely agree on an ideal cabin temperature; clothing, sun exposure and individual sensitivity all shift the preference. Talking it through before departure is simpler than renegotiating it repeatedly once everyone is settled.
Safety and Driver Assistance
Locating lights, wipers, mirrors and door releases while stationary takes only a moment and removes guesswork later. Passengers gain from it too, since a driver who is not hunting for a switch can answer questions calmly.
Multimedia and Connectivity
Battery level becomes a shared concern when one phone handles directions for everyone. Where a charging point is available, deciding who uses it keeps that need separate from taking a call or choosing what plays.
