NullReferenceException in Two Scripts

I Got NullReferenceException when trying to access variable from another script, also if someone could advise me in improving the code would be great. Any help appreciated.

The script im tryin accessing from: (Accessed variable is set as public float vec$$anonymous$$clespeed)

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class MoveCars : MonoBehaviour
 {
 
 
     public float vec$$anonymous$$clespeed;
     private bool stopped = false;
     private float stoptime;
 
 
     // Use t$$anonymous$$s for initialization
     void Start()
     {
         stopped = false;
         vec$$anonymous$$clespeed = 10;
     }
 
     void CarMoves()
     {
         transform.Translate(Vector3.forward * vec$$anonymous$$clespeed * Time.deltaTime);
     }
 
     void CarStops()
     {
         stopped = true;
         stoptime = 1;
         //Debug.Log("Hamuje");
     }
 
     // Update is called once per frame
     void Update()
     {
         if (stopped == false)
             {
             CarMoves();
             }
                               
         if (stoptime > 0)
             {
             stoptime = stoptime - 1 * Time.deltaTime; //Debug.Log(stoptime);
             }
 
         //if (vec$$anonymous$$clespeed > 0) { vec$$anonymous$$clespeed = vec$$anonymous$$clespeed - 1; }
         // transform.Translate(Vector3.forward * vec$$anonymous$$clespeed * Time.deltaTime);
         if (stoptime == 0)
             {
             stopped = false;
             }
     }
 
                   
     
 
     void OnTriggerEnter(Collider other)
     {
         CarStops();
     }
 
     /*
     void OnTriggerStay(Collider other)
     {
         CarStops();
         //Debug.Log("Stoi");
     }
     */
 
     void OnTriggerExit(Collider other)
     {
         stopped = false;
         stoptime = 0;
         //Debug.Log("Rusza");
     }
 
 
 
 }
     

And the script in w$$anonymous$$ch im tryin to change accessed value (anotherscript.vec$$anonymous$$clespeed in Void SpawnVec$$anonymous$$cles with no success):
