Destroy Object from prefabList

Unity Engine

Hey folks,

I need your help regarding the Destroy method.
I want to destroy a car, when it has driven by and it cannot be seen in the camera anymore.
I used a Trigger to destroy the “Tile” when it passed by but as the cars are in a prefabList, I cannot select a specific object to destroy.
I made a video to demonstrate my problem and attached my code for the car spawning below.

Thank you so much for your help!

Kind regards
Tim

public class CarSpawn : MonoBehaviour
{
    List<GameObject> prefabList = new List<GameObject>();
    public GameObject carSpawnGreen;
    public GameObject carSpawnBlue;
    public GameObject carSpawnPolice;
    public GameObject carSpawnBus;
    public GameObject carSpawnVan;
    public GameObject carSpawn1;

    public GameObject carSpawn7;
    public GameObject carSpawn8;
    public float speed = 30F;
    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(Waiter());
        prefabList.Add(carSpawnBlue);
        prefabList.Add(carSpawnGreen);
        prefabList.Add(carSpawnPolice);
        prefabList.Add(carSpawnBus);
        prefabList.Add(carSpawnVan);
        prefabList.Add(carSpawn1);

        prefabList.Add(carSpawn6);
        prefabList.Add(carSpawn7);
        prefabList.Add(carSpawn8);
    }

    {
        int prefabIndex = Random.Range(0, 8);
        int wait_time = Random.Range(1, 5);
        yield return new WaitForSeconds(wait_time);
        int carPicker = Random.Range(1, 3);
        if (carPicker == 1)
        {
            Instantiate(prefabList[prefabIndex], new Vector3(44.49F, 0.85F, 100F), Quaternion.Euler(new Vector3(0F, 90, 0F)), transform);
        }
        else
        {
            Instantiate(prefabList[prefabIndex], new Vector3(47.21F, 0.85F, 100F), Quaternion.Euler(new Vector3(0F, 90, 0F)), transform);
        }

        StartCoroutine(Waiter());
    }

    // Update is called once per frame
    void Update()
    {
        transform.Translate(Vector3.back * speed * Time.deltaTime);
    }

    private void OnTriggerEnter(Collider other)
    {
        //Destroy cars when touching the trigger
    }
}

Silly question, why destroy a car rather than store it in an object pool?

You have a fundamental flaw above: your spawner is trying to figure out who died when they hit the trigger.

Bluntly that is none of the business of the spawner. That’s the business of the car to decide.

Therefore, instead put a script to destroy the car ON THE CAR, and have that respond to the trigger and destroy itself.

Go look at pretty much any tutorial on triggers or colliders to see this in action.
