Comfort and Convenience
Power mirrors separate the two actions: the switch selects which mirror is live, then a directional control tilts the glass itself. Aiming is done from the seat, not by pushing the housing by hand.
Safety and Driver Assistance
ABS acts after the driver has already decided to brake hard. It senses a wheel about to lock and eases pressure many times a second, something no pedal foot can modulate by observation alone.
Multimedia and Connectivity
The audio system handles the amplification stage: it takes a low-level signal from a radio tuner or a connected source and drives the speakers, adjusting volume, balance and tone along the way.
