Comfort and Convenience
Power mirrors move the glass by small motors on a switch command, so the driver sets the angle from the seat. They reposition the view but cannot remove the blind zone beside the car, which still needs a shoulder check before a lane change.
Safety and Driver Assistance
The driver's airbag reacts only after a crash sensor confirms a severe frontal impact: a gas generator fires and the cushion inflates through the steering wheel hub, then vents so the torso decelerates against the belt rather than the rim.
