Answer 1

To simply turn the direction you want would cause you to fall over. Your wheels can move left while your body keeps going straight. You counter steer to use this to your advantage. You steer the wrong direction to cause you to fall in the opposite direction, the direction you want to turn in. Now your body is going left and you can turn your wheels left so you can keep your body over the wheels and stay balanced.
