The self-parking technology that Ford developed uses ultrasonic sensors on both the front and the rear of the car, along with an electronic power steering system to angle and guide the car into a snug parking space all just by pressing a simple button that says Self-Park.
Some people may be saying that Ford is not the first company to introduce a self-parking car. While that is true, Ford is introducing the first of its kind, a much more versatile self-parking system. It is the only system that allows for self-parking on a slope.
In that sense the ease of self-parking also comes with an added advantage, proper parallel parking on slopes, which may potentially prevent a ghastly car accident caused by an improperly parked car rolling down a hill.
