Comfort and Convenience
Cabin temperature is a common source of disagreement. People feel warmth differently depending on clothing and seating position, so front and rear occupants often prefer noticeably different settings on the same journey.
Safety and Driver Assistance
Controls are easiest to learn while the car is stationary. Knowing roughly where the hazard switch or demister sits means less time spent looking down and hunting across the dashboard.
Multimedia and Connectivity
Hands-free calling and music playback are handled separately by most systems, whatever connection is used. Confirming that one works does not mean the other will, so each is worth trying.
