Laravel , how to call a function from another controller

I have a controller with the "getUsers" function in a controller called "UserController" , and inside it I want to call a function of the "CarController" controller called "getCars", the two options I have are:

a) Make the second call as "static" , then I can call it without instantiating the class

b) Do not do that function of the static class and I call it in this way

    $ car_id = 100;
    $ userController = new UserController ();
    $ userController-> getCars ($ car_id);

I do not know which is the best practice, or what pros or cons has one or another.

I'm using laravel. Thanxs.
