Even when I lived in rural East TX I didn’t leave my keys in my car. I admit when I was younger I used to leave my purse in my car (but locked) but I don’t do that any more since it’s in invitation for someone to break my window to steal my purse.
But, you may never have a problem. I just don’t know why anyone would tempt fate.
If I worked 10 miles south of here I would never consider it.
