On the picture below you will see imaginary intersecting lines going through the centers of the wheels. The intersection point is the center of the turn.

If you allow the car to turn long enough, it will draw a circle around the intersection point. The wheels will also move along the circle, as shown on the picture below:

As you can see, the distance covered by the inner wheels is considerably shorter. Therefore, to make the car move normally, the speed rates at which the rear wheels go should have the same correlation as the two circles. As this task is still difficult for you, you can download the following block which will drive the motors.
