Why can't they make 4-door cars with rear windows that go all the way down? I don't have any kids and my friends would like to rest their arms on the door. My old dog would have loved it if the rear windows could have been rolled all the way down. He had to rest his head lightly on the glass to get a breeze (he was a good boy, I never had to worry about him jumping out). I know it's done to protect kids but we should have the option of not getting it. They have things where the driver can lock the windows entirely, so why can't we have an option where we can roll them all the way down and lock them halfway if need be? I know it's stupid but it always bothered me.
