This is why should rub your car windshield with a potato. How many times have woke up to find a cold frozen car windshield?
My old friend, who I like o call Brother Moon says this not only is delaying the departure to our destination, but it is a nuisance and a hassle. Our options are to scrape off the ice or deice the windshield with a store-bought or homemade deicer or use a cut piece of potato. https://youtu.be/AErz6zswKxc
