Comfort and Convenience
Warmth is a good example: some people want the cabin heated quickly, others prefer air cool and moving. The same setting reads as pleasant or stifling depending on clothing, and on who sits alongside.
Safety and Driver Assistance
Preparation is simple: sort the seat and mirrors, then locate the hazard switch and demister while the car is still stationary. Doing that in a quiet moment beats hunting for a control at a junction.
Multimedia and Connectivity
Taking a call without handling the phone depends on audio and microphone duties sitting with the car rather than the handset. If such a function is present, music pauses and resumes around the conversation.
