Driving D.R.i.V.e

I have reconsidered the way that D.R.i.V.e steers himself. Before this D.R.i.V.e.'s steering was using the two back motors one turning clockwise and the other turning anti-clockwise therefore turning it while the front motor pulls the car forward. Now I have altered D.R.i.V.e's steering to more like the modern car's steering to make the wheels  swivel therefore making it more ordinary.Using the base of a Race Car Program I created a swivel.
