fix script to get C# var from another object instead of object this script is attached to

Question

I have this script which in theory I want it to disable the player's C# car controller script when the game over canvas it's attached to is enabled when the race is over. The problems I'm having that this script setup only works for other C# scripts that are attached to the object that has this script? To fix this is it as easy as putting the player object in a GameObject variable and just edit the GetComponent action to have the script find the player's controller script?

 public class GameOverPause2P : MonoBehaviour {
     public PlayerCar scriptPlayerCar;
     public PlayerCar2 scriptPlayerCar2;
 
     void Start()
     {
         scriptPlayerCar = GetComponent<PlayerCar> ();
         scritpPlayerCar2 = GetComponent<PlayerCar2> ();
         scriptPlayerCar.enabled = false;
         scriptPlayerCar2.enabled = false;
 
     }
     
     // Update is called once per frame
     void Update () {
         
     }
 }

sounds like using static variables might be an easy solution if have a condition that is to be shared by all your cars. then no look ups are necessary.

     public static bool RaceIsOver;
 
         void Update () {
         if (RaceIsOver==true) {
 
             //if ANY car changes the bool to true
             // all cars will do this here 
             //because static variables are
             // shared by all
 
                 }
     
     }

if you want to change or check a static variable from another script you simply would say:

     //no lookup nessesary!!!!
     nameOfScript.RaceIsOver = true;

      public class GameOverPause2P : MonoBehaviour {
 
      // reference the player GO's in order to retrieve their respective script components
      public GameObject PlayerCar1;
      public GameObject PlayerCar2;
      public PlayerCar scriptPlayerCar;
      public PlayerCar2 scriptPlayerCar2;
 
      // game over is false by default
      public bool GameOver = false;
 
  
      void Start()
      {
 
         // grab the script component for both players
         Player1CarControllerScript = PlayerCar1.GetComponent<ScriptPlayerCar>();
         Player2CarControllerScript = PlayerCar2.GetComponent<ScriptPlayerCar2>();
 
          scriptPlayerCar = GetComponent<PlayerCar> ();
          scriptPlayerCar2 = GetComponent<PlayerCar2> ();
          scriptPlayerCar.enabled = false;
          scriptPlayerCar2.enabled = false;
  
      }
      
      // Update is called once per frame
      void Update () {
 
         if (GameOver == true) {
 
             // disable CarControllerScript component attached to player
             Player1CarControllerScript.enabled = false;
             Player2CarControllerScript.enabled = false;
 
         }
      
      }
  }
