Is there a way to make the four switchLane functions into one function and randomizing which lane it chooses to switch to? [duplicate]

I am making a car game where the enemies have behaviour where to move to a specefic point on the road I already have the 4 points but I don't know how to randomize where the enemy prefab moves to I have to change it manually now. I would really appreciate some help and thank you already. I am a beginner at coding so take it easy ;)

using System.Collections.Generic;
using UnityEngine;

public class EnemyScript : MonoBehaviour
{
    public float speed;
    private GameObject playerTransform;
    private GameObject enemyCarPrefab;
    private float distanceToNextCar;
    public float distance;

    private float roadWidth;
    private float lane1 = 7.25f;
    private float lane2 = 2.45f;
    private float lane3 = 2.4f;
    private float lane4 = 7.3f;


    // Start is called before the first frame update
    void Start()
    {
       
    }

    // Update is called once per frame
    void Update()
    {

        playerTransform = GameObject.FindGameObjectWithTag("Player");
        enemyCarPrefab = GameObject.FindGameObjectWithTag("BaseCar");

        distanceToNextCar = enemyCarPrefab.transform.position.z - distance;
        if (playerTransform.transform.position.z > distanceToNextCar)
        {
            switchLane1();
        }
    }


    private void switchLane1()
    {
        Vector3 targetPos1 = new Vector3(-lane1, 0, 0);
