Sample quote

The cameras are also smaller than traditional side-view mirrors, which means that they generate less wind noise, reduce the vehicle's drag coefficient, and obtrude less in the driver's field of vision when cornering or manoeuvring.

Housed in aerodynamic casings to reduce their exposure to dust and rain, the cameras are equipped with built-in heaters to prevent freezing or misting, they also have luminescence sensors that automatically reduce the glare from the headlamps of other automobiles.
