Comfort and Convenience
Power mirrors matter most just before setting off: a switch drives small motors in each housing, so the glass can be aimed from the seated driving position without reaching across the cabin or stepping outside.
Safety and Driver Assistance
Lane departure warning reads lane markings and alerts on unsignalled drift, so it addresses lateral position only. Nothing in that function measures the gap ahead, which still depends entirely on the following distance chosen.
Multimedia and Connectivity
Bluetooth provides the wireless link itself, pairing a handset to the car so audio streams and call data travel over that connection instead of a cable, which is what lets hands-free calling work.
