Comfort and Convenience
People rarely agree on cabin temperature. Someone sitting in direct sunlight usually wants it cooler than a passenger in shade, which is why occupants often ask for different settings on the same trip.
Safety and Driver Assistance
Setting the mirrors and seat while stationary is far simpler than attempting it in moving traffic, and the same applies to learning how the stalks behind the steering wheel are arranged.
Multimedia and Connectivity
Hands-free calling generally depends on pairing the phone beforehand. Without that step, a call stays on the handset instead of moving to the car's speakers and microphone.
