A $2,200 add-on to the new Toyota Prius hybrid car allows the car to parallel-park itself, using a sensor array.
A dashboard display shows the image taken by the camera. When you near a parking space and shift into reverse, computerized lines pop up on the display, along with arrows pointing up, down, left and right.
Using the arrows, you move the lines around until they define exactly where you want the car to be parked. Then you push the "set" button on the display.
Keep your foot lightly on the brake pedal, and the car will start backing up, the steering wheel responding to an invisible hand. Voila, the car will park itself in the spot you've chosen with the arrows.
