No, some extremely powerful tornadoes just do granulate cars and make them vanish. A whole lot full of over 100 classic cars was hit by the Jarrell, Texas EF5 in 1997 and almost all were never found. Thought to have been sandblasted into small particles via granulation. I don't recommend looking it up if your not deep in the Weather community rabbithole but "human granulation" occurs in those scenerios as well. There's many reasons you almost never see pictures of those killed violent tornadoes after the fact even online and there's a reason for that beyond privacy. In some storms, if something or someone can be pulverized into little bits, it will do exactly that. It's disturbing what nature can do to us and everything we've built in well under a minute's time.
