Probably the coolest feature on the new Lexus LS600hl is the new Driver Monitor System with a face detection camera, mounted on the top of the steering wheel. If the camera detects that it appears the driver is not looking directly ahead for a few seconds or more, and if an obstacle is detected ahead, then it alerts the driver first with a warning chime and a flashing light. As the car gets closer to the obstacle, APCS can begin to gently apply the brakes on its own. To assist the driver in maneuvering around the obstacle, the system reprograms the steering ratio, amplifying the intensity and quickness of the steering response. Moreover, it can reportedly "reprogram the steering ratio and amplify the intensity and quickness of the steering response" to keep motorists safe, but there's no word on whether or not a retinal scanner add-on will be available to automatically adjust user preferences depending on which driver hops in the seat.
