My idea will give a better and more cheap way of changing lanes, while still making it safer. For all new drivers, this idea will be perfect for them. As sensors are attached to the bumper of cars, and then linked to the dashboard of the car, they can sense large objects nearby. A red, yellow, green iglht scheme is set up on the dashboard. With these three colors, the ultrasonuc sensor can sense 10 feet, which will light up green, 7 feet, which will light up yellow, and 5 feet, which will light up red to sense that a object is really close.
