Mercedes-Benz: Attention Assist[16] In 2009, Mercedes-Benz unveiled a system called Attention Assist which monitors the driver's fatigue level and drowsiness based on his/her driving inputs. It issues a visual and audible alarm to alert the driver if he or she is too drowsy to continue driving. It is linked to the car's navigation system, and using that data, it can tell the driver where coffee and fuel are available.[17] Cadillac: GM 2018 Cadillac CT6 Super Cruise System, The Cadillac Super Cruise system uses FOVIO vision technology, developed by Seeing Machines , to enable a gumdrop-sized infrared camera on the steering wheel column to accurately determine the driver's attention state.
