How to make ai move like my character but without controls

I am trying to make a hover craft game and i have a hovercraft that moves perfectly using values from the users controls but i have a problem with getting the AI to move like the main character here is the code i use to control the player

 using UnityEngine;
 using System.Collections;
 using UnityStandardAssets.CrossPlatformInput;
 
 public class CarController : MonoBehaviour {
 
     //Values that control the vehicle 
     public float acceleration;
     public float rotationRate;
 
     //values for faking a nice turn display
     public float turnRotationAngle;
     public float turnRotationSeekSpeed;
 
     //Reference variables we dont directly use
     private float rotationVelocity;
     private float groundAngleVElocity;
 
     //Weapons variables
     public Transform[] laserSpawnPoints;
     public GameObject projectile;
     public float ShootForce;
 
     //Initialization code here
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         Shoot();
     }
 
     void FixedUpdate()
     {
         Move();
         
     }
 
     void Move()
     {
         //Check if we are touching the ground 
         if (Physics.Raycast(transform.position, transform.up * -1, 3f))
         {
             //We are on the ground; enable the accelerator and increase drag
             GetComponent<Rigidbody>().drag = 1;
 
             //Calculate forward force
             Vector3 forwardForce = transform.forward * acceleration * CrossPlatformInputManager.GetAxis("Vertical");
             //Correct force for deltaTime and vehicle mass
             forwardForce = forwardForce * Time.deltaTime * GetComponent<Rigidbody>().mass;
 
             GetComponent<Rigidbody>().AddForce(forwardForce);
 
         }
         else
         {
             //We are not  on the ground and do not want to just halt in mid-air; reduce drag
             GetComponent<Rigidbody>().drag = 0;
         }
 
         //You can turn in the air or on the ground
         Vector3 turnTorque = Vector3.up * rotationRate * CrossPlatformInputManager.GetAxis("Horizontal");
         //Correct force for deltaTime and vehicle mass
         turnTorque = turnTorque * Time.deltaTime * GetComponent<Rigidbody>().mass;
         GetComponent<Rigidbody>().AddTorque(turnTorque);
 
         //Fake rotate the car when you are turning
         Vector3 newRotation = transform.eulerAngles;
         newRotation.z = Mathf.SmoothDampAngle(newRotation.z, CrossPlatformInputManager.GetAxis("Horizontal") * -turnRotationAngle, ref rotationVelocity, turnRotationSeekSpeed);
         transform.eulerAngles = newRotation;
     }
 
     void Shoot()
     {
         if (Input.GetButtonDown("Fire1"))
         {
             for (int i = 0; i < laserSpawnPoints.Length; i++)
             {
                 GameObject proj = (GameObject)Instantiate(projectile, laserSpawnPoints[i].position, laserSpawnPoints[i].rotation);
                 proj.GetComponent<Rigidbody>().AddForce(laserSpawnPoints[i].forward * ShootForce, ForceMode.Impulse);
             }
         }
     }
 }
 

I am new to this please i need help
