As we move ever closer to the driverless car, Mobileye takes a step backward with its automatic warning system (AWS), a color-coded indicator that mounts on your dashboard. Its eye is actually a small video camera mounted to the rear view mirror, and its image processor, called the EyeQ, calculates the distance between your car and the one in front of you, giving you an audible and visual warning if you get too close. It also lets you know if you drift out of your lane, but is deactivated if you turn on the car's turn signal.
Come to think of it, you could just avoid spending the $1800 for this unit and judge the distance between you and that car in front of you with your own two eyes. If that's not enough, get married and you'll have an auto-nagging device sitting right next to you.
