The driving feature uses sensors on the left and right of the car to tell it how far it is from the side walls. It turns left and right depending on how far it is from the sides. If it is closer to the left wall it will turn right and vise versa. In the video it may seem if the car is very wobbly, but that is because I'm limited by how fast the processor is and the speed the wheels can turn. In the future it could be much smoother.
