Comfort and Convenience
Cabin temperature is the classic point of disagreement: one occupant feels cool exactly where another feels warm. Preferences shift with clothing, seating position and plain personal sensitivity, so shared journeys usually involve a little quiet negotiation.
Safety and Driver Assistance
Finding the hazard lights, the demister and the mirror adjustment while still parked is easier than hunting for them in moving traffic. A minute of preparation means fewer unfamiliar reaches once passengers are aboard and the journey is under way.
Multimedia and Connectivity
Battery level is the usual worry on longer shared trips, because passengers navigate, message and read along the way. Where charging is available in the cabin, it simply means a phone reaches the destination still usable.
