If your turn signals were broken on your car, would you lower the window and give a signal with your arm?

I actually saw a farmer on a tractor do this the other day. i was shocked. he apparently had no turn signals on his old country tractor, but at least he obeyed the law. if your car’s turn signals were inoperative, would you or have you ever lowered the window and given a turn signal with your arm? i have seen many bike riders do this and i am amazed. ok, have you or have you not ever given a turn signal with your arm?
