BMW's Latest Sedan Allows Drivers to Change Lanes with Eye Movements.

BMW has unveiled its new 5-series sedan with an optional Highway Assistant system that allows drivers to change lanes just by looking at one of the outside mirrors. The car's automated driving system suggests a lane change if the car ahead is going too slowly, and the driver only has to look at the corresponding side mirror for the car to do the rest. The system relies on a camera mounted behind the steering to monitor the direction of the driver's gaze and check that the driver is watching the road at all times.
