can i change this into UI controls ??

 var WheelFR : WheelCollider;
  var WheelFL : WheelCollider;
  var WheelRR : WheelCollider;
  var WheelRL : WheelCollider;
  
  var Speed = 10;
  var Braking = 20;
  var Turning = 20;
  
  function Update ()
  {
      //This code makes the car go forward
      WheelRR.motorTorque = Input.GetAxis("Vertical") * Speed;
      WheelRL.motorTorque = Input.GetAxis("Vertical") * Speed;
      
      WheelRR.brakeTorque = 0;
      WheelRL.brakeTorque = 0;
      
      //This code makes the car turn
      WheelFL.steerAngle = Input.GetAxis("Horizontal") * Turning;
      WheelFR.steerAngle = Input.GetAxis("Horizontal") * Turning;
      
      //This code puts brakes on the car
      if ( Input.GetKey(KeyCode.Space)) 
      {
          WheelRL.brakeTorque = Braking;
          WheelRR.brakeTorque = Braking;
      }
  }
