BLIS (Blind Spot Information System) Volvo
This highly effective device uses digital cameras incorporated in the door mirrors to monitor the 'blind spot' and alert the driver of other road users by a flashing light inside the car next to the appropriate mirror. It is able to distinguish between moving and immobile objects so that it does not give false alarms from parked cars and street furniture. Especially useful on crowded motorways. First demonstrated on the Volvo Safety Concept Car in 2001, BLIS is now available as a option on most of the Volvo range.
