Unity Application.Quit() doesn't work

Question

In the update, I have set up a counter so that after 140 frames, Unity will quit the game. But this quit command doesn't quit and it just continues to play the game. What am I doing wrong? I am using and testing in Unity 2D. There are no errors and all the prints are visible.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Normal_Car : MonoBehaviour
{
    private int counter = 0;

    public Vector3 finalPos = new Vector3(0.00f,0.00f,0.00f);

    public Transform t;

    // Start is called before the first frame update
    void Start()
    {
        t.GetComponent<Transform>();
    }

    // Update is called once per frame
    void Update()
    {
        print("Frame: " + counter.ToString());
        counter += 1;
        t.position += finalPos;
        if(counter >= 140)
        {
            Application.Quit();
            print("Quit!");
        }
    }
}

Answer 1

If you check out the documentation for Application.Quit it starts by saying this:

Quits the player application. Shut down the running application. The Application.Quit call is ignored in the Editor.

Application.Quit does nothing if you test inside the editor.

Answer 2

I think it's this.Quit(); That might just be in WinForms though :)
