Comfort and Convenience
The on-board computer gathers trip data and shows it on the instrument display; scrolling between readouts is usually done from the multifunction steering wheel rather than a separate panel.
Safety and Driver Assistance
On a slippery bend the car can begin to rotate more or less than the steering asks. ESP brakes individual wheels to counter that yaw, but grip still limits what it can recover.
Multimedia and Connectivity
Bluetooth pairs a phone wirelessly, so the audio system receives the stream and the track titles sent by the handset; selection can then happen on either device.
