Hey guys, I'm basically new with scripting and I have a scripting problem that a I cannot solve in my java script. What I'm trying to do is to create a car simulation, there is still a lot that I will add to the script in the future to make it more realistic. Also, there is a tiny part of a commentary section that I plan to use with a steering wheel rather than the keyboard as my input.

Here is the code:

 #pragma strict
 var WheelLFCollider : WheelCollider;
 var WheelRFCollider : WheelCollider;
 var WheelLRCollider : WheelCollider;
 var WheelRRCollider : WheelCollider;
 var WheelLF : Transform;
 var WheelRF : Transform;
 var WheelLR : Transform;
 var WheelRR : Transform;
 var lowestSteerAtSpeed : float = 50;
 var lowSpeedSteerAngle : float = 10;
 var highSpeedSteerAngle : float = 1;
 var decelerationSpeed : float = 30;
 var maxTorque : float = 50;
 var currentSpeed : float;
 var topSpeed : float = 150;
 var rb: Rigidbody;
 
 function Start () {
 rb = GetComponent.<Rigidbody>() ;    
 }
 
 function FixedUpdate () {
 Controle ();
 }
 
 function Update() {
 WheelLF.Rotate(WheelLFCollider.rpm/60*360*Time.deltaTime,0,0);
 WheelRF.Rotate(WheelRFCollider.rpm/60*360*Time.deltaTime,0,0);
 WheelLR.Rotate(WheelLRCollider.rpm/60*360*Time.deltaTime,0,0);
 WheelRR.Rotate(WheelRRCollider.rpm/60*360*Time.deltaTime,0,0);
 WheelLF.localEulerAngles.y = WheelLFCollider.steerAngle - WheelLF.localEulerAngles.z;
 WheelRF.localEulerAngles.y = WheelRFCollider.steerAngle - WheelRF.localEulerAngles.z;
 }
 
 function Controle () {
 //var Accel = Input.GetAxisRaw("Accelerator") ;
 //Debug.Log(Accel);
 currentSpeed = 2*22/7*WheelLRCollider.radius*WheelLRCollider.rpm*60/1000;
 currentSpeed = Mathf.Round(currentSpeed);
 
 if (currentSpeed < topSpeed) {
 WheelRRCollider.motorTorque = maxTorque * Input.GetAxis("Vertcial");
 WheelLRCollider.motorTorque = maxTorque * Input.GetAxis("Vertical");
 }
 
 else {
 WheelRRCollider.motorTorque = 0;
 WheelLRCollider.motorTorque = 0;
 }
 
 if (Input.GetButton("Vertical")==false) {
 WheelRRCollider.brakeTorque = decelerationSpeed;
 WheelLRCollider.brakeTorque = decelerationSpeed;
 }
 
 else{
 WheelRRCollider.brakeTorque = 0;
 WheelLRCollider.brakeTorque = 0;
 }
 
 if (Input.GetAxis("Vertical")){
         rb.velocity = Vector3(50,0,0);
         }
 
 var speedFactor = GetComponent<Rigidbody(rb.velocity.magnitude/lowestSteerAtSpeed);
 var currentSteerAngle = Mathf.Lerp(lowSpeedSteerAngle,highSpeedSteerAngle,speedFactor);
 currentSteerAngle *= Input.GetAxis("Horizontal");
 WheelLFCollider.steerAngle = currentSteerAngle;
 WheelRFCollider.steerAngle = currentSteerAngle;
 }
