Comfort and Convenience
Cabin temperature comfort is personal: some people prefer a steady cool airflow, while others want warm air only after the engine has built heat.
Safety and Driver Assistance
Practicing mirror adjustment and gear selection while parked lets a driver build muscle memory before dealing with traffic.
Multimedia and Connectivity
Phone calls in a moving car work best when the microphone can isolate the driver's voice, so the phone's position matters even if it is paired wirelessly.
