Our car looks like four wheels, two in the front close together and two are in the back separated, and a small wheel in the back. Now we added that small wheel because we noticed that our car, wouldn't go straight it would go either left or right. But when we added the small wheel into the back or in the middle of the body, it made the car straight but yeah it slows it down a little bit but the good thing is, is that it goes straight and at least it doesn't go to the left or right. But it still goes a bit the left or right and we're thinking maybe adding breaks into the car.

Great response! Keep up the good work!
