Comfort and Convenience
An on-board computer is always running; the driver only chooses which readout appears. That differs from dual-zone climate control, where each side is actively set to a chosen level rather than simply displayed.
Safety and Driver Assistance
The anti-lock braking system governs the braking moment itself, releasing and reapplying pressure at a wheel that is about to lock so the tyres keep turning and steering input still has an effect.
Multimedia and Connectivity
Android Auto passes a connected phone's compatible apps to the vehicle's own display and controls, so navigation or audio is selected through the car rather than by handling the handset.
