get in get out of a car. Unet

I am making multiplayer fps shooter, and it works perfectly, but when it comes to vehicles i got some problems, cause i am kinda new to Unet. I wrote script for getting in the vehicle and it works normally, for singleplayer and i have no idea how to implement this into multiplayer, i tried these "ClientRpc" stuff, (didnt work), "Command" and etc. so basically Player has Controll script (which i use for moving him) and this script has function OnControllerColliderHit, so if this happens i call void Disable(); here is script anyways: `

     void OnControllerColliderHit(ControllerColliderHit hit)
     {
         //so if we hit car
         if(hit.collider.tag == "Vehicle")
         {
             //if we pressed "E"
             if (Input.GetKeyDown(KeyCode.E))
             {
                 //call method to disable some stuff taht should be disabled, like: controller, shoot, weapons etc.
                 disable(inVehicle, hit);
             }
         }
     }
 
 
     //method to disable some stuff taht should be disabled.
     void disable(bool inVehicle, ControllerColliderHit hit)
     {
 
         //Vehicle has script PlayerControll (not for moving player, just stupid name), where it controlls how many players are in car, is there driver or not, etc.
         hit.gameObject.GetComponent<PlayerControll>().CmdSit(transform.name); //yeah, i am trying [Command] thing here.
         inVehicle = true;
 
         //character cntroller is disabled;
         cc.enabled = !inVehicle;
 
 
         //if it is not localplayer, so for other players: my colldiers should be disabled....
         if (!isLocalPlayer)
         {
             for (int i = 0; i < disableForRemote.Length; i++)
             {
                 disableForRemote[i].SetActive(!inVehicle);
             }
         }
         // as well as mine for me lol.
         else
         {
             for (int i = 0; i < disableForClient.Length; i++)
             {
                 disableForClient[i].SetActive(!inVehicle);
             }
         }
         //disabling scriptsssssss....
         for(int i = 0; i< disableComponentForClientAndRemote.Length; i++)
         {
             disableComponentForClientAndRemote[i].enabled = false;
         }
     }

(pls read them it's not big, just comments)

and My "PlayerControll script (that is NOT for controlling/moving player, just name...)"

 using UnityEngine;
 using System.Collections;
 using UnityEngine.Networking;
 public class PlayerControll : NetworkBehaviour {
 
 
     //max players in vehicle. (lol why 1?? :DDD)
     public int MaxPlayers = 1;
 
 
     //cammera
     public Camera cam;
 
     //Sync var so every player can know how many of players are in the car.
     [SyncVar]
     public int sitPlayers;
 
 
     //Sync var so every player can know does this car have driver or not(none of them is not working BTW. as well as network transform. )
     [SyncVar]
     public bool hasDriver = false;
 
 
     //this is where i "teleport" player that became driver of car. and i make player child of Driver GO.
     public GameObject Driver;
     //same here but for passanger.
     public GameObject Sitter;
 
     void Start()
     {
         cam.enabled = false;
         cam.GetComponent<AudioListener>().enabled = false;
 
         GetComponent<AudioSource>().Play();
     }
 
     void Update()
     {
         //if there is driver in car then we can controll it. (it's a paradox for me, if there is driver and i am passanger i also can controll it lol.)
         if(hasDriver)
         {
             GetComponent<carController>().enabled = true;
         }
         else
         {
             GetComponent<carController>().enabled = false;
         }
     }
 
     //command function for sitting. in car.
     [Command]
     public void CmdSit(string _player)
     {
         //i increase how many people are in car
         sitPlayers++;
 
         cam.enabled = true;
         //find player who sat there.
         GameObject player = GameObject.Find(_player);
 
 
 
         //i think you will get it >>
         if (hasDriver)
         {
             player.transform.parent = Sitter.transform;
             player.transform.position = Sitter.transform.position;
             cam.GetComponent<AudioListener>().enabled = true;
 
            
         }
         else
         {
             player.transform.parent = Driver.transform;
             hasDriver = true;
             cam.GetComponent<AudioListener>().enabled = true;
             player.transform.position = Driver.transform.position;
         }
 
 
     }
 
     //"Unet is easy" they said....
     void Out()
     {
         //havent made i yeeeet.
     }
 
 }
